Match the solutions List-I with change in their properties in List -II and select correct code. [Assume no change in volume on addition of solute/reagent] List - I List - II (I) 10 milli moles of HgI

Question

Match the solutions List-I with change in their properties in List -II and select correct code. [Assume no change in volume on addition of solute/reagent]

List - I	List - II
(I) 10 milli moles of $HgI_{2}$ are added to 10 ml of 2 M aqueous KI.	(P) Osmotic pressure of solution increases
(II) 50 milli moles of KI are added to 20 ml of 0.5 M aqueous $CuSO_{4}$ .	(Q) Freezing point of solution increases
(III) 10 milli moles of $FeCl_{2}$ are added to 20 ml of 3 M aqueous KCN .	(R) Vapour pressure of solution increases
(IV) 10 milli moles of $HgCl_{2}$ is added to 10 mL of $1 M (NH_{4})_{2} [Co (SCN)_{4}]$	(S) Boiling point of solution increases

HgI₂ + 2KI → K₂[HgI₄] FeCl₂ + 6KCN → K₄[Fe(CN)₆] + 2KCl 2CuSO₄ + 5KI → Cu₂I₂(s) + 2K₂SO₄ + KI₃ HgCl₂ + (NH₄) 2 [Co(SCN)₄] → 2NH₄Cl + Co[Hg(SCN)₄]↓
