Question

Which of following

solutions will have maximum boiling point elevation and which have minimum freezing

point depression assuming the complete dissociation?
(a) 0.1 m KCl
(b) 0.05 m NaCl

(c) 1m AlPO4

(d) 0.1 m MgSO4​

Answer 1

$\huge\star\mathfrak\red{{Answer:-}}$

Solution : Boiling point elevation and

freezing point depression are colligative

properties that depend on number of particles in solution. The solution having more number of particles will have large boiling point elevation and that having less number of particles would show minimum freezing point depression.
