The Effect of Sucrose Solution Concentration on Osmosis in Potato Chips

Plan

I am going to cut six pieces of potato using a borer. They will all

the same weight. I will make them all 0.7g. I will be able to make

sure they are all the same weight-using scales. If a piece of potato

is too big I will use a scalpel and a tile to trim it so they are all

the same weight and then place these into a test tube each. I will

hold the test tubes in a test tube rack. Using the measuring cylinder

I will measure 10ml of each strength of sugar solution rinsing the

measuring cylinder after each measure. This will then be added into

separate test tubes with the pieces of potato. E.g. a piece of potato

will have 0.0M strength; a piece of potato will have 0.2M strength and

a piece of potato will have 0.4M strength etc. I will put a sticky

label on each test tube stating what strength of sugar solution it

contains. I will then leave these for 2 hours and see what happens

then record my results.

APPARATUS

A potato

Sugar solutions (0.0, 0.2, 0.4, 0.6, 0.8, and 1.0)

Borer

Scalpel

Tweezers

Scales

6 test tubes

Test tube rack

Measuring cylinder

I will measure the amount of sugar solution in the test tubes. I will

change the strength of sugar solution in each test tube. To make the

experiment a fair test I will keep the weight of the pieces the same

weight I will also only add the same amount of sugar solution. I think

that the higher the molar used the lighter the weight of the potato

chip after the experiment. I believe this will happen because osmosis

is the movement of high concentration ton low concentration.
