Solutions · Osmosis and osmotic pressure

At 27∘^\circC, 0.1 M, 1 L KX4[Fe(CN)X6]\ce{K4[Fe(CN)6]} aqueous solution and 0.1 M, 1 L FeClX3\ce{FeCl3} aqueous solution are placed in a container separated by a semi permeable membrane AB. Assume complete dissociation of both the solutes. Which of the following statement is correct ?
  1. (1)Blue color is formed on both sides.
  2. (2)Ionic solutes in aqueous solution can pass through semi-permeable membrane.
  3. (3)Solution on side ‘y' is hypotonic.
  4. (4)To cause the reverse flow of solvent during osmosis, external pressure (any value) should be applied to side ‘x'.
