Effect of Sucrose Solution on Osmosis
Effect of Sucrose Solution on Osmosis
Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes.
Osmosis is the movement of water molecules across a partially permeable membrane from a high water concentration to a low water concentration. Osmosis can be effected different things such as:
- Temperature - The warmer the solution, the quicker the osmosis will go. This is because the water molecules will be moving more quickly.
- Difference in concentrations - This will speed up the rate of osmosis because there will be more particles that'll have to change places. - Surface Area - This will speed up the rate of osmosis because there will be more space on the potato for osmosis to take place.
- Concentration of water in potato - the higher the concentration of water in the potato the quicker osmosis will happen because less water will have to diffuse into the potato to even the amounts of water inside and outside the potato.
So Osmosis is basically a special kind of diffusion involving water molecules, which occurs when two solutions are separated by a partially permeable membrane. The water diffuses from the weaker solution to the stronger solution. Tiny holes in the membrane allow small water molecules to pass through, but the glucose molecules are too large to pass through the semi- permeable membrane.

Prediction: I predict that as I increase the concentration of sucrose high or low, the amount of water moving in or out the potato will change. Sucrose or distilled water will make the potato increase in length and mass. Water will move into the
