Question

What will be the change of vapour pressure when HgI2 is added to KI solution ?​

Answer 1

Answer:

Answer:KI forms a complex with HgI2.

Answer:KI forms a complex with HgI2.2KI + HgI2 → K2HgI4

Answer:KI forms a complex with HgI2.2KI + HgI2 → K2HgI4Therefore, the number of particles in solution decreases resulting in the decrease in relative lowering of vapour pressure. Hence, vapour pressure increases.
