MCQ
What is the molar solubility of :- $Ag_2CO_3 (K_{sp} = 4 \times 10^{-13})$ in $0.1\, M\,Na_2CO_3$ solution?
- ✓$10^{-6}$
- B$10^{-7}$
- C$2 \times 10^{-6}$
- D$2 \times 10^{-7}$
$\mathrm{Na}_{2} \mathrm{CO}_{3} \rightarrow\left[\mathrm{CO}_{3}^{-2}\right]=0.1$
$\mathrm{K}_{\mathrm{sp}}=\left[\mathrm{Ag}^{+}\right]^{2} \times\left[\mathrm{CO}_{3}^{-2}\right]$
$4 \times 10^{-13}=(2 s)^{2} \times(s+0.1)$
$ \downarrow $
Neglected
$s=10^{-6}$
