Q.
A litre of solution is saturated with $AgCl$.To this solution if $1.0 \times 10^{- 4}$ mole of solid $NaCl$ is added, what will be the $\lbrack Ag^{+}\rbrack$ assuming no volume change?
A) More
B) Less
C) Equal
D) Zero
Explanation
(b)
$AgCl \rightarrow Ag^{+} + Cl^{-}$
$X\ \ \ \ \ \ \ \ \ X$
After NaCl is added $\ \ \ \ \ \ \ \ \ \ \ \ \ \ X\ \ \ \ \ \ \ X + 1 \times 10^{- 4}$
That is why $Ag^{+}$ will be less
