Potato Osmosis Lab Report
bring upIn this experiment was designed to study the effect of a concentrated solution applied to sporting and clean potatoes. The solutions impact among the potatoes were to be either hypertonic, hypotonic, or isotonic. The potatoes were first cut into heat with a chela cutter, and then weighed after being cut. The white and engaging potatoes weights ranged from .005-.015 grams.A total of 18 edulcorate solutions are to be made over the course of 3 trials. In individually trial, 6 diametric types of solutions are to be made. (0% sugar, 10% sugar, 20% sugar, 30% sugar, 40% sugar, and 50% sugar). For each trial, in 6 plastic cups, pour 100mL of water, combine the sugar that in which corresponds to the percentage of sugar, and place one potato fry in each cup. In the first and second trials, enforce the sweet potatoes. In the third trial, manipulation the white potatoes. LABELTHE CUPS ACCORDING TO THE MIXED SOLUTION Leave the potatoes to sit for a 24-hour period.Introduction Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute assiduousness in the presence of water. An isotonic solution is one in which the concentration of solutes is the same inside the electric carrel as outside the cell (STAYS THE SAME). A hypotonic solution testament have a get down concentration of solutes than the cell (SWELLS).A hypertonic solution will have a higher concentration of solutes than the cell and will have a higher osmotic pressure outside the cell than inside the cell. (SHRINKS) The prey of this experiment was to study the effects of one concentrated solution (with different percentages of solute) on white and sweet potatoes. If a .015 white potato is placed in solution with 50% sugar, then it will subdue (Hypotonic)Materials Sugar Water Potato Fry Cutter Plastic Cups Black Permanent Marker gradatory Cylinder 1 Sweet Potato 1 White PotatoProcedures1.Accumulate 1 white and 1 sweet po tato. 2.Cut potatoes into fries with a fry cutter and weigh 12 white potato fries and 6 sweet potato fries. 3.For each trial, in 6 plastic cups, pour 100mL of water, combine the sugar that in which corresponds to the percentage of sugar. LABEL THE CUPS 4.Place one potato fry in each cup. 5.In the first and second trials, use the sweet potatoes. In the third trial, use the white potatoes. 6.Leave the potato fries to sit for 24-hours.Controls The controls include the time, temperature, and 100mL of each water, ETC. Independent Variables The independent variables include the solutions tested, ETC. Dependent Variables The potatoes ability to swell, shrink or confirmation the same, ETC.Conclusion Through experimentation, If a .015 white potato is placed in solution with 50% sugar, then it will shrink hypothesis was accurately proved. To further better this experiment, I would extend the time over a course of 2 hours and would test the experiment outside on the sun.Questions What causes sugar to shrink and swell things? wherefore did some potatoes swell and others didnt that had the same weight and percentage of sugar?
