Use the scales to check the weights of the potato strips are all 2. Place each strip in a test tube, marked out with its morality of sucrose solution.

The morality is the way that you should always refer to the solutions. Remove the pieces of potato, dry them on a cloth or piece of tissue, so that no fluid is left on the outside of the potato. Weigh each of the pieces separately and make a note of the weight.

Fairness If everything is cut exactly, weighs the same and volumes in the syringes are exact, the tests should be accurate.

The data obtained can be called reliable if the test is repeated to give a better idea of the spread of the results. Safety Do nt hold potato in your hand whilst boring, make sure you do it on a work surface.

Take care when using scalpel, as it is surgically sharp. When working with glass test tubes, make sure that all bags and chairs are kept out of the way, and do not run, weather or not you are holding the test tubes.

Predictions I predict that as the water potential outside of the potato increases, so too will the weights. This is because the water molecules pass from a high concentration, i. In the water itself, to a low concentration, i.

In the potato chip. Therefore, the chips in higher water concentrations will have a larger mass than in higher sugar concentrations. I would estimate that as the morality of the solution decreases by a factor of 2 i.

Osmosis in Potatoes Essay - Osmosis in Potatoes My main aim in this experiment is to find out if osmosis occurs in a potato, and how it affect the potato in different molar solutions of sucrose and water, and finally the approximate morality of the potato.

The basic principles of Osmosis and Diffusion were tested and examined in this lab. We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. As osmosis is defined as the movement of water molecules across a partially permeable membrane from an area of high water concentration to an area of low water concentration, I predict that as the water concentration decreases in the potato pieces the overall mass and length will decrease too.
