Question

The diffusion the movement of molecules is random and the independent of each other . What is iys meaning ?

Answer 1

It means that the molecules diffusing from one medium to another are independent of each other. The flow of molecules is random or unplanned, i.e. as soon as the molecules come in contact with a dilute solution or a solution in which solute concentration is low, they would diffuse into that solution to balance the concentration of solutes among the two media.
