Solution

The correct option is D Less
A litre of solution is saturated with $A g C l$ .

To this solution if $1.0 \times 10^{- 4}$ mole of solid $N a C l$ is added, $[A g^{+}]$ will be less.

$A g C l ⇌ A g^{+} + C l^{-}$
$N a C l \to N a^{+} + C l^{-}$

Thus, the dissociation of $N a C l$ provides chloride ions that are common to $A g C l$ . Due to common ion effect, the dissociation of $A g C l$ is suppressed and $[A g^{+}]$ decreases.

Hence, option B is correct.
