The Effect of Different Concentration of Salt Solutions on Potato Tissue

Title: An investigation into the affect of different concentration

salt solutions on potato tissue

Aim: .I have to find out the effect of varying salt concentrations on

a potato tissue. Also to find out how osmosis occurs with different

salt concentrations from very dilute to very concentrated. I will be

looking for any changes in mass and length

Prediction: I predict that the most concentrated salt solution (1

molar) will be the solution that will have the most dramatic effect

upon the tissue of the potato. As the solution goes down the line in

other words gets more and more dilute or weaker it will have a less

distinctive effect upon the potato tissue. This will happen due to the

high concentrated solution i.e. the 1 molar salt solution moving

across into a low concentrated are i.e. the potato chip. The potato

chips that are in the most concentrated solutions will be the ones,

which will lose mass. The potato chips which will be in the diluted

solutions will gain more mass this is the actual osmosis scientific

theory. Osmosis is the movement of water molecules from an area of

high water concentration through a semi-permeable membrane to an area

of low water concentration. This is very similar to diffusion and

active transport.
