Question

When mercuric iodide is added to the aqueous solution of potassium iodide,the

Answer 1

Hey !!

Kl reacts with HgI₂ to form a complex as

2Kl + HgI₂ -----> K₂[HgI₄] --(ionizes)--> (2K⁺ + 2I⁻) 2 K⁺ + HgI₄²⁻

Thus, number of ions decreases in the solution. Hence, depression in freezing point is less actual freezing point is raised.

Hope it helps you !!
