To create an isotonic solution that potatoes can be stored in
Aim: I will create a solution that will be perfect for storing potato chips in. This solution must have a perfect concentration of salt to water, so creating an isotonic solution, which will stop osmosis occurring so neither causing the potatoes cells to swell up or shrivel up.
Variables: To make sure my results are valid I must take into account the variables that may affect my experiment like;
- Temperature- changes in temperature can speed up or slow down reaction times.
- Size/mass of potato chips- the size and mass of a potato chip can affect the experiment as the larger the potato chip is more osmosis can occur.
Simple plan: I will use four different solutions each with a different concentration of salt to water. I will put each solution into a separate beaker then I will place a potato chip in each of these solutions.
