Salt Concentration During Osmosis

Osmosis Potato Lab If the c at at one timentration of flavor urine were to annex would it decrease the crispness of the spud? Hypothesis: I see that higher the denseness of the salt water goes, the less(prenominal) curt the stump spud will be. This will happen because when the intentness of the salt in the water turn upside the potato is very(prenominal) high, the water in the potato will move out to cause equilibrium cause the walls of the cell to weaken, shrivel, and for the potato to be lighter1. And so in theory, it would plant sense if the higher the concentration is the to a greater extent water would leave the potato. Variables: nonparasitic: Concentration of salt water pendant: Crispness by determining the change in great deal of potato Controlled: Type of potato, amount of salt water, temperature, time, same method of standard Materials: 1 Potato 250 ml beaker 10%, 20%, 30% concentrations of salt water Knife Stop finder bare bill of fare/ Cutting tiles Digital scales A ruler Tray Method: 1.First, visualise a potato and using a knife, cut up 3 small bits of potato 2.Weigh the slice of potatoes, and try to off it each of them approximately 2.5 grams 3.Record the weight of each piece of potato 4.

Lay the pieces of potato into the tray, make sure they are as spread out in the tray 5.Using the beaker, effuse 100ml of 10% salt water into the beaker 6.With a stopwatch in hand, once you pour all of the salt water into the tray, immediately locomote the watch 7.Leave the pieces of potato in the tray for 2 hours 35 minut es 8. once the time is up, take the potatoe! s out of the tray 9.Weight them individually and immortalise the results 10. civilise each of the recorded mass from before the examine and compute it with the recorded mass from after the experiment 11.This will know you the mass that the pieces of potatoes have lost after the experiment 12.Add 3 of the results up and then divide them by 3 to reveal the average for each piece 13.Now,...If you want to get a unspoiled essay, order it on our website: OrderCustomPaper.com
