In the following reaction.
`AgCl +KI hArr KCl +AgI`
as KI is added, the equilibrium is shifted towards right giving more AgI precipitate , because

A

both AgCl and AgI are sparingly soluble

B

the `K_(sp)` of AgI is lower than `K_(sp)` of AgCl

C

the `K_(sp)` of AgI is higher than `K_(sp)` of AgCl

D

both AgCl and AgI have same solubility product

Text Solution

Verified by Experts

The correct Answer is:
B
On adding KI, the equilibrium
`AgCl+KI hArr KCl +AgI`
is shifted towards right. This means that AgI is less soluble than AgCl. In other words `K_(sp)` of AgI is less than `K_(sp)` of AgCl.
