Acids be very(prenominal) caustic substances that can break beat materials easily. The gamey ge ber window glassity obtained by a substance, the faster it is able to decompose a nonher material. In fiat to determine the acidity of certain substances, a pH scale is used. On this scale, numbers unrivaled to fourteen are placed. Fourteen would represent an increased amount of alkalinity rather than acidity.Seven is a neutral z sensation, and one would be an increased amount of acidity rather than alkalinity (USGS, 2016). Figure 1 shows how the scale works and a select few substances that obtain different pH values. These values range from 14 to 1. The greater acidity of a substance, the more pernicious it is. The firster acidity of a substance, the less corrosive it becomes. In order to determine the perniciousness of a material, a pH scale is used. Testing strips help determine this.A pH testing strip is a member of paper that is used to measure the molar concentration of hy drogen ions to determine the acidity or basicity of a substance (GSU, 2000). The use of pH testing strips write out plentiful information when trying to obtain the pH of a substance.Figure 1 Standard pH Scale (BIOL 1406)Soft DrinksStudies take a crap provided information that many of commercially change low-key suck ups in the United States are utmost(a)ly corrosive with a pH of 4.0 or lower.The average wastefulness of tooth structure begins at 4.0 (Zhejiang University, 2009). Thus stated, these diffuse drinks maintain a detrimentally high erosive potential and are able to cause diarrhoea. The soft drink Pepsi has a pH of 2.37. Orange take apart importanttains a pH of 2.87. Dr. Pepper reveals a pH of 2.88. Country Time Lemonade shows a pH of 2.57, and coca plant poop contains a pH of 2.39 (Reddy, et. Al., 2015).Pepsi has the lowest pH of these select soft drinks, so it has the highest acidulous level, whereas Dr. Pepper has the highest pH. Concluding this, Pepsi is th e most corrosive substance, and Dr. Pepper is the to the lowest degree corrosive. Since the dissolution of atomic number 20 begins at 4.0, every soft drink used in this poll is of great detrimental damage. The erosive potential of each drink has a great effect on structures such as enamel. The fastest dissolution would begin with Pepsi, coca Cola next, then Country Time lemonade.After lemonade, Orange Crush, and finally Dr.Pepper.Calcium And DissolutionCalcium is a mineral that supplies the main structure and hardness for trick outs and odontiasis. (Goldblatt, et. Al, 2016). It is also the backbone of nut case welts, for the protective coating around the egg is made of calcium carbonate. The calcium differences between tooth enamel and egg scolds are very closely related. They are not the akin, but in comparison, their properties correspond very well.Enamel consist of minerals that help protect the tooth. This is the selfsame(prenominal) for pelthells. Eggshells are a pro tective coating for the egg. Yet, while tooth enamel contains calcium phosphate, eggshells contain calcium carbonate (University of Illinois, 2016). Eggs appear to be the beaver direct comparison to find closely related results. If a soft drink can decompose an eggshell in a certain amount of time, it should likewise be the same for enamel, moreover a bit more complicated because of the excess mineral makeup that makes teeth a stronger substance.The calcium carbonate and the soda are the lawful reactions. Its not so much the egg as a whole, or the soda as a whole, it is how they act amongst each other when combined. The acidic drink is eligible to break down calcium levels because of the reaction between the substances. Enamel begins to increasingly dissolute inversely to the increase of pH. As the pH lessens, the more dissolution is caused ( Larsen, 1999). Soda contains many different levels of sugary and acidic values that cause a much faster dissolution, and cause erosion.Usin g a demonstration of teeth submerged in an acidic liquid for a week is close to a life time span of drinking soda end-to-end some(prenominal) years. This is understandable because the structure is submerged inside the liquid at all times, not just frequent periods (Swains, 2007). How Dissolution in Enamel Works Because of the high phosphoric acid content in carbonated drinks, they are seemingly low on the pH Scale. Low pH levels are extremely acidic and remineralize particles in tooth enamel.Dissolution causes dental problems over time. Some of these painful diseases are caused by soft drinks. Some common issues seen amongst people that have a nutrition containing soda everyday are more susceptible to caries, osteoporosis, attrition, and abstraction(American Dental Association, 2000).The phosphoric acid and sugar compounds create a massive build up a suck inst bone structure. Although enamel is strong and sturdy, dissolution begins at surroundings of a 4.0 pH, so it doesnt hold u p forever. Carbonated drinks are express to be just as bad as non diluted vinegar, but because of all of the sugars and artificial flavoring, the drinks do not seem as bad. In fact, some carbonated drinks are of a lower pH than vinegar on the pH scale( Austin Community College).The initial purpose of this experiment was to enhance the knowledge of what drinks can decompose calcium the fastest due to specific levels of acidity.Discussion True dissolution did not seem to begin until after the first week. In comparison to a life span, one week is a reasonable amount of time before decay because 1 week is a regular sitting of soda over a 3 year time span. It is known that dissolution does not begin right away, more so it is the long term effects after something has been through repeatedly. (Swains, 2007)The eggshells had absorbed the distorts of the drinks. This was very intricate because the soft drink seemed to appear disoluted, whereas the egg had pertained the saturation of color. In comparison, teeth absorb the color of drinks and stain after a while. Of course this is not shown right away, but as stated previously, the time frame in which the eggs soak is an approximation of almost xiii years of drinking that drink regularly.This is a valid point as to why the egg had such a large discoloration it was because it absorbed the color it was surrounded by (W3C, 2006). The acidic drinks used had a detrimental change on the eggshells. The mass of the eggs decreased sufficiently and distinctively. When touching the shell, it was fragile, and the drinks were so corrosive that the shell itself was stripping into thin sediment. Pieces of the shell were flaking off. Soft drinks have such a high phosphoric acid content which virtuosos to extreme reductions of calcium.Reductions of calcium lead to weak and fragile structures. Pepsi Eggs that had been submerged in Pepsi were sticky and had a brown overtone to them. These eggs had gone through the most dissolution thro ughout the 4 week timespan. This makes sense when understanding that the most acidic substance used was Pepsi. Pepsi has a very low pH balance which causes such an extreme amount of dissolution. The more acidic a substance is, the more corrosive and efficient it is when eroding.With a pH of 2.37, it is easy to tell that the substance has a high acidic ranking which is a detrimate factor in erosion. The net hit dissolution caused by the soft drink Pepsi was .847g. Pepsi is a Cola product so the assumption was that it would have taken a toll like Coca Cola did, but it turns out it was a handle harsher on the eggs than Coca Cola was. Frankly, It was approximately double the damage. The American Dental Association provides information on Cola products and the way they affect bone structure.Cola products are said to be a significant cause of damage to the bones which explains why the eggshell had dissoluted so quickly in Pepsi. But why not the same for Coca Cola too? This is where the phosphoric acid in Pepsi was higher than in Coca Cola. Pepsi had a lower pH, so it was more corrosive afterall ( American Dental Association, 2000).Orange Crush Eggs that were submerged in Orange Crush had many interesting effects to them. The most interesting was that the egg shell had gained the saturation of the drink whereas the drink diluted to almost a complete clear color. Although this toped, it did not have a great amount of dissolution as expected. Orange juice is very acidic, but because there was a use of mainly carbonated sodas, Orange Crush seemed like the next best comparison. on that point was not as much damage as expected after all with only .359g disoluted total. It is still a great amount of dissolution, but not as much as the Cola products and Country Time Lemonade. Orange Crush obtained the second lowest pH of all the substances( American Dental Association, 2000). Although the phosphoric acid was lower than most of the solutions, Dr. Pepper still had the lowe st pH and phosphoric acid level of all.Nonetheless, Orange Crush still contains a low pH, phosphoric acid, and is eligible to be abrasive to structure. The acids present take on considerable influences of demineralizing and causing attrition in structures( Johansson, et Al. 2012). Dr. Pepper Eggs that were submerged in Dr. Pepper were sticky and obtained a similar brown color like the eggs submerged in Pepsi. The solution had made a sort of adhesive protection around the egg much like Pepsi had.By the fourth week each egg was completely brown and the shell was softened reservation it substantially weaker than the first week. Although the shell was weak. Eggs submerged in Dr. Pepper had the least dissolution amongst every soft drink. Considering the pH of Dr. Pepper is the highest, at just 2.88,and it obtains the least acidic makeup this is of validation. Although, Dr. Pepper contains a higher sugar concentration than most drinks.This partakes a great roll in the occurrence of diss olution too. Sugary drinks affect dissolution as much as acid concentration, so there was still a great potential of attrition to occur over the four week time period(Ophardt, 2003). When calculating the average dissolution amongst all of the soft drinks, Dr.Pepper did appear to have the lowest in dissolution. The net total was .243g. This is a smaller number compared to the rest of the soft drinks, yet nonetheless it is still an amount of dissolution.Concluding this, it is still a corrosive substance also. These acid and sugar contents are detrimental to structure(Thompson, 2016).Country Time Lemonade Eggs that were submerged in Country Time Lemonade contained a very gritty texture and the shell was flaking off into small pieces that were brittle and thin. The Country Time Lemonade had also bleached the eggshell.By the fourth week, the eggshells had been brightly shining as a pure white, whereas when the eggs first began they were dull and had very light grey spots in select places . Some pieces of the shells were gone and the inside was preserved like a coating of yolk that was rubbery. Although brittle and frail, the most dissolution was not caused by Country Time Lemonade. The net total dissolution had actually fallen directly in the middle of all soft drinks.The total abrasion of the eggs submerged in Country Time Lemonade amounted .369g. Although a smaller amount than Coca Cola and Pepsi, there was still a substantial amount of dissolution amongst these eggs over all( American Dental Association, 2000). One of the biggest factors that Country Time Lemonade is eligible to exert such a great dissolution is because of the acid in lemons/ lemon juice and the amount of sugar added to this solution.As well as the low pH balance of 2.57. A considerable amount of dissolution occurs under these conditions(Ophardt, 2003). Coca ColaEggs submerged in Coca Cola had the second highest erosive potential amongst this castigate of carbonated drinks. Much like the ending results of Dr. Pepper and Pepsi, Coca Cola also had the same sticky coating around its shell and the discoloration of the egg was brown as well. The solution was gooey just as Dr. Pepper and had a very soft texture to it.The shell was mushy and turned very fragile over each week. By the fourth week, the eggs submerged in Coca Cola were just completely mushy and didnt have stableness to them at all, whatsoever. Cola products are severely detrimental to structures. They cause a critical dissolution amongst structures, in this case eggs. Coca Cola is said to be significant in causing bone damage. Coca Cola and Pepsi are both products of Cola, but Coca Cola had a lessened effect on the eggs. The phosphoric acid and sugar contents contained in the soft drink Coca Cola were less than in the solution, Pepsi.Through the comparison of Cola products, it was center to see which would substance had the greatest effect. Originally, it was thought that Coca Cola would cause the most dissolution because it is such a strong acidic drink and had a high sugar content. Needless to say, this wasnt the case, and Pepsis acidic content was higher thus leading it to have a lower pH. Although Coca Cola did not have a significant amount of dissolution compared to Pepsi, it still ranked number two out of five. With a dissolution of .447g over the 24 day span, Coca Cola provided the second most decrease( American Dental Association).With a pH balance of and a high sugar content, Coca Cola was able to gain second, yet Pepsi still has Coca Cola beat.In conclusion, the carbonated drinks presented in this essay have provided a true presentation of how the dissolution of eggshells resemble the abfraction and attrition of tooth enamel( Fraunhofer, 2006).These drinks are hard on enamel. The effects stay for a lifetime, and can cause many problem areas.Carbonated drinks cause lesions, caries, and can even cause osteoporosis in actual bone structures by draining the calcium levels in your body. The effects of these soft drinks are not kind on the body. Consuming these acidic substances sets up a lifetime of problems that make you much more susceptible to enamel decay. It is okay to drink these drinks, but it is a must to do it in a moderate way. These substances contain such high acidic levels that cause demineralization in enamel.The phosphorus content of soft drinks can even limit the calcium absorption which can lead to bone loss due to diseases such as osteoporosis(American Dental Association). Some carbonated drinks affect erosion a lot less than others, but this does not add limitations for these carbonated drinks are still detrimental to ones health. Between soft drinks, Pepsi is definitely the most detrimental of all, and Dr. Pepper is the least detrimental.If carbonated soft drinks are a want, or need, this poll provides a considerate amount of information as to why Dr. Pepper would be the best option. It is still unhealthy and can cause erosion, but of the drink s, it seems to be the best option. Eggs provided a great substitute for teeth in this project. The two structures have so many common features that made it a lot easier to make a comparison. The limitations of calcium absorption played a huge part in creating this project(Texas University, 2016). The final data was fascinating to compare. The results were not the same as the hypothesis, but that made the final results the most riveting of all.
