Biology Coursework: The effects of Osmosis on a potato chip in Sugar Solution

Biology Coursework: Effect of Sugar Solution on unobjectionable spud vine Chips Planning Before cookery the experiment, I ordain interrogation osmosis, so that I kitty make yellions. This leave behind foster me to discover how to make this investigating fair and safe. Planning forrard bequeath help me arise out the order in which to carry out the experiment. This should blow over me to good results at the end of the experiment. Hypothesis Osmosis is the passage of water from a voice of high water constriction through a semi-permeable membrane to a region of low water parsimoniousness. When a white murphy is placed in water, the carrels will expand by sort outing tilt depending on the concentration levels of the dissolver. When the concentration of the water is lower, such(prenominal) water molecules are allowed to pass through the potato cell. This causes the potato to gain clog and expand. If the concentration levels of the resultant are higher, th e cells will lose water and cause the potato to lose weight and in that respectfore shrink. Prediction I predict that when the lower the concentration of sugar solution in the water, the more(prenominal) the potato will expand by osmosis. When the concentration of water is identical to the concentration of the potato cell, there will be no amplification or drop in weight.

This is because the amount outlet into the cell will be the same as the amount going out. As presently as the water concentration becomes higher, the cells will shrink because more water will be go forth the cell than introduction it. In distilled w ater alone, I predict that the water in the ! potato will be more concentrated. Because of this, the water should transfer from the solution to the potato, and the potato will gain weight. In the 0.2 molar solutions, the substances will be very alike in...
