$A g_{2} C r O_{4} ⇌ 2 A g^{+} + C r O_{4}^{2 -}$

$2.2 \times 10^{- 4} 1.1 \times 10^{- 4}$

$K S P = {(2.2 \times 10^{- 4})}^{2} (1.1 \times 10^{- 4})$

$= 5.3 \times 10^{- 12}$

Solution

Q.
Concentration of $A g^{+}$ ions in a saturated solution of $A g_{2} C r O_{4}$ is $2.2 \times 10^{- 4} m o l L^{- 1}$ . Solubility product of $A g_{2} C r O_{4}$ is :-

1 $2.66 \times 10^{- 12}$

2 $4.5 \times 10^{- 11}$

3 $5.3 \times 10^{- 12}$

4 $2.42 \times 10^{- 8}$
