In 1 L saturated solution of AgCl [ K _ sp ( AgCl )=1.6 10^ -10 ]… - Vidyadip

MCQ

In $1 L$ saturated solution of $AgCl \left[ K _{ sp }( AgCl )=1.6 \times 10^{-10}\right]$, $0.1$ mol of CuCl $\left[ K _{ sp }( CuCl )=1.0 \times 10^{-6}\right]$ is added. The resultant concentration of $Ag ^{+}$in the solution is $1.6 \times 10^{-x}$. The value of " $x$ " is

✓
$7$
B
$8$
C
$9$
D
$2$

Answer

Correct option: A.

$7$

a
It is a case of simultaneous solubility of salts with a common ion. Here, solubility product of CuCl is much greater than that of AgCl , it can be assumed that $Cl ^{-}$in solution comes mainly from CuCl .

$\left[ Cl ^{-}\right]=\sqrt{ K _{ sp }( CuCl )}=10^{-3} M$

Now, for $AgCl , K _{ sp }=1.6 \times 10^{-10}=\left[ Ag ^{+}\right]\left[ Cl ^{-}\right]$

$=\left[ Ag ^{+}\right] \times 10^{-3}$

$\Rightarrow \quad\left[ Ag ^{+}\right]=1.6 \times 10^{-7}$

$\text { Hence, } x=7$
