Question

Maximum depression in freezing point is caused by (A) potassium chloride (B) sodium sulphate (C) magnesium sulphate (D) magnesium carbonate

Tardigrade Admin · Accepted Answer

Depression in freezing point is a colligative property, so depends upon the number of particles. Among, potassium chloride

(K Cl)

, sodium sulphate

(N a_{2} S O_{4})

, magnesium sulphate

(M g S O_{4})

and magnesium carbonate

(M g C O_{3}), N a_{2} S O_{4}

produces maximum number of particles.

N a_{2} S O_{4} ⇌ 3 particles 2 N a^{+} + S O_{4}^{2 -}

Thus, it causes maximum depression in freezing point.
