The potato tubes will all be cut out of the potato using a cork borer and will all be cut to the length of 25mm. This will remain constant throughout each experiment. Each of the 5 times I do the experiment, I will increase the concentration of the solution by 0.25 mols/dm³, starting from just water in, going up to 0.25 mols/dm³, 0.50 mols/dm³, 0.75 mols/dm³ and finally 1.00 mol/dm³. The solution shall be my variable. The other variables I could have used are: - The temperature of the solution. - The size of the potato cylinders. - The...
