The Effect of Glucose Concentration on the Rate of Osmosis

Aims

In this investigation Ill be working to know:
How does the intentness of glucose termination affect the rate of osmosis in potato chips?
Why does the concentration of glucose solution affect the rate of osmosis in potato chips?
How does the surge of potato chips changes in different concentration glucose solutions?

Introduction

The purpose of this investigation is to observe the factors that affect the rate of osmosis in potato chips and check out the pretendment of osmosis done the cells of potato.

Diffusion

Diffusion is the net movement of particles from a region of high-pitched concentration to a region of first base concentration until the concentrations are equal. The speed of diffusion depends n the disagreements amongst the concentrations to begin with.

Osmosis is a special type of diffusion, it occurs across a permeable membrane which allows some particles to diffuse through it and go along others. Therefore osmosis is the passage of peeing from a region of high concentration to a region of low concentration through a semi-permeable membrane.




The direction and the rate of osmosis depend on the difference in body of piss concentration between the two sides of the membrane and this movement bequeath continue until equilibrium is reached.
Cell membranes will allow small molecules like oxygen or water or carbon dioxide or glucose to pass through moreover they will prevent larger molecules like sucrose or starch or protein to pass through.
The tendency of water to move through a partially permeable membrane is exposit as its water potentiality and is at a supreme in pure water. As solutes are added the water potential lowers and this means that more concentrated solutions read lower water potentials than more stretch solutions and so the water will have a greater tendency to move from pure water to any aqueous solution and from a more dilute solution to a more concentrated solution.
