TS EAMCET 4-Aug-2021 Shift 2 Question Paper

MgCl2 and BaCl2 both have van't Hoff factor (i) three. Hence, more the ions are dissociated from a single formula unit, more will be value of i.
[i∝∆Ti]∴∆Ti= colligative properties
Hence, higher the value of i, more will be colligative properties for the same concentration.
For NaCl; van't Hoff factor is i=2, so, it has lesser colligative properties than MgCl2 and BaCl2.
