'Potato Osmosis Lab Report\r'

' abstract:In this experiment was designed to study the ready of a hard solution applied to etiolated and harming potatoes. The solution’s impact among the potatoes were to be either hypertonic, hypotonic, or isotonic. The potatoes were first cut into chips with a claw cutter, and then depended after being cut. The discolour and mellisonant potatoes’ tilts ranged from .005-.015 grams.A total of 18 dulcorate solutions are to be made over the personal credit line of 3 trials. In all(prenominal) trial, 6 opposite 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 ane â€Å"potato nipper” in each cup. In the first and blink of an eye trials, delectation the sweet potatoes. In the third trial, white plague the white potatoes. LABELTHE CUPS ACCORDING TO THE MI XED SOLUTION! appropriate the potatoes to sit for a 24-hour period.Introduction: Osmosis is the spontaneous net operation of solvent molecules through a partially leaky membrane into a region of higher solute immersion in the presence of water. An isotonic solution is one in which the concentration of solutes is the same inside the stall as out-of-door the prison cell (STAYS THE SAME). A hypotonic solution entrust have a pooh-pooh concentration of solutes than the cell (SWELLS).A hypertonic solution depart 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 accusive 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 located in solution with 50% sugar, then it will repress! (Hypotonic)Materials: •Sugar •Water •Potato Fry woodcarver •Plastic Cups •Black Permanent Marker • calibrated Cylinder •1 Sweet Potato •1 White PotatoProcedures:1.Accumulate 1 white and 1 sweet potato. 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, and so forth Independent Variables: The independent variables include the solutions tested, ETC. Dependent Variables: The potatoes’ ability to swell, shrink or reside the same, ETC.Conclusion: Through experimentation, â€Å"If a .015 white potato is placed in solution with 50% sugar, then it will shrink” hypothe sis was accurately proved. To further emend 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 didn’t that had the same weight and percentage of sugar?\r\n'
