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
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
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
- 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... [continues]
