Salt Concentration During Osmosis

Osmosis Potato Lab
If the c at oncentration of flavor urine were to annex would it decrease the crispness of the potato?

Hypothesis: I see that higher the concentration of the salt water goes, the less curt the potato will be. This will happen because when the concentration of the salt in the water outside the potato is very 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:

Independent: 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 measuring

Materials:
1 Potato
250 ml beaker
10%, 20%, 30% concentrations of salt water
Knife
Stopwatch
bare board/ Cutting tiles
Digital scales
A ruler
Tray

Method:
1.First, view a potato and using a knife, cut up 3 small bits of potato
2.Weigh the slice of potatoes, and try to make 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, pour 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 minutes
8. once the time is up, take the potatoes out of the tray
9.Weight them individually and immortalise the results
10. Take each of the recorded mass from before the examine and subtract it with the recorded mass from after the experiment
11.This will distinguish 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 die the average for each piece
