The solubility of \[AgI\] in \[NaI\] solution is less than that in pure water because             [UPSEAT 2001]

A)                 AgI forms complex with NaI

B)                 Of common ion effect

C)                 Solubility product of AgI is less than that of NaI

D)                 The temperature of the solution decreases

Correct Answer: B

Solution :

           Solubility is decreased due to common ion effect.                    \[AgI\] ⇌\[A{{g}^{+}}+\,\,\,\,{{I}^{-}}\]                        \[NaI\] ⇌ \[N{{a}^{+}}+\,\,\,\,{{I}^{-}}\]
