What is Diffusion Experiment with Dialysis Tubing about?

Diffusion is the movement of molecules or ions from an area of high concentration to low concentration. In this experiment, dialysis tubing acted as a selectively permeable membrane. In beaker A, NaOH molecules diffused through the tubing, turning the solution inside pink due to reaction with phenolphthalein indicator. In beaker B, iodine molecules diffused through and reacted with starch inside the tubing, turning the solution blue-black. Both reactions demonstrated diffusion of smaller molecules through t
