Question

Solubility of AgCl in water 0.01M $CaC{l}_2$, 0.01M NaCl and 0.05M $AgN{O}_3$ are $S_1,S_2,S_3$ and $S_4$ respectively then $(K_{sp}AgCl={10}^{-10}{M}^2)$

• A. > > >
• B. > > >
• C. > = >
• D. > > <

Answer 1

The correct option is B > > >

$AgCl\rightleftharpoons A{g}^{+}+c{l}^{-}$
$lnCaC{l}_2$
$CaC{l}_2\rightleftharpoons C{a}^{+2}+2C{l}^{-}$
$0.02M$
$lnNaCl$
$NaCl\rightleftharpoons N{a}^{+}+C{l}^{-}$
$0.01M$
$lnAgN{O}_3$
$AgN{O}_3\rightleftharpoons A{g}^{+}+N{O}_3^{-}$
$0.05$
Common ion effect is maximum in $AgN{O}_3$ etc
$S_1$ > $S_3$ > $S_2$ > $S_4$
