Freezing point is raised

Vedclass · Answer

(B) When $CuSO_4$ is added to an aqueous ammonia solution,it forms a complex ion $[Cu(NH_3)_4]^{2+}$.This reaction reduces the total number of solute particles in the solution.According to colligative properties,the depression in freezing point $(\Delta T_f = i 	imes K_f 	imes m)$ and elevation in boiling point $(\Delta T_b = i 	imes K_b 	imes m)$ are directly proportional to the van 't Hoff factor $(i)$.Since the number of particles decreases,the van 't Hoff factor $(i)$ decreases.Consequently,the freezing point of the solution increases (less depression) and the boiling point decreases (less elevation).

When $CuSO_4$ is added to a solution of ammonia,what happens to the boiling point and freezing point of the solution?
