Effect of different sucrose concentration solutions on potato samples. Aim In order to find out how the mass of potato samples are affected by various concentrations of sucrose solution, I will use six concentrations ranging from a 1-mol dm­³ solution to distilled water (0 mol dm­³). The effects upon the potato samples will be concluded by comparing the mass of the sample before and after being placed in their solution. I predict that a unique type of diffusion called osmosis will affect the mass of the potato samples in their sucrose solutions. Background Diffusion is defined as the net movement of molecules (or ions) from a region of their higher concentration to lower concentration: down a concentration gradient. However, osmosis is a unique type of diffusion as it only involves water molecules. During osmosis, the energy of the water molecules tendency to move from one region to another, by exerting pressure on the...
