Statement  Formation of semipermeable membrane between the walls of porous pot on hanging pot filled with `CuSO_(4) (aq.)` partiallt dipped in `K_(4)Fe(CN)_(6)` is due to osmosis.    Explanation   The ions moves through the walls of porous pot and between the walls `Cu^(2+)` and `Fe(CN)_(6)^(4-)` gives insoluble gelatinous mass of `Ca_(2)[Fe(CN)_(6)]_(4)`.
