To Investigate the Effect of Osmosis on Equal Length Potatoes Aim The aim of this experiment is to measure the loss of sugar (sucrose) from potatoes, which have been affected by Osmosis. In this experiment, I have Dependent and Independent variables. My dependent variables will be; * Type of potatoes * Mass of potatoes * Length of potatoes * Time left in Sucrose solution My Independent variable will be; * Molar amount Background Information Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permeable membrane is one that allows unrestricted passage of water, but not solute molecules or ions. Different concentrations of solute molecules lead to different concentrations of free water molecules on either side of the membrane. On the side of the membrane with higher free water concentration (i.e. a lower concentration of solute), more water molecules will strike the pores...
