Concentration of the Ag^{+} ions in a saturated solution of Ag_{2} C_{2} O_{4} is 2.2 \times 1 0^{- 4} mol L^{- 1} . Solubility product of Ag_{2} C_{2} O_{4} is:

Solution & Step-by-step Explanation

For the salt Ag_{2} C_{2} O_{4} : Ag_{2} C_{2} O_{4} (s) ⇌ 2 Ag^{+} (a q) + C_{2} O_{4}^{2 -} (a q) Let the solubility be s . Then [Ag^{+}] = 2 s and [C_{2} O_{4}^{2 -}] = s .Given [Ag^{+}] = 2.2 \times 1 0^{- 4} M, so s = \frac{2.2 \times 1 0 ^{- 4}}{2} = 1.1 \times 1 0^{- 4} M . K_{s p} = [Ag^{+}]^{2} [C_{2} O_{4}^{2 -}] = (2.2 \times 1 0^{- 4})^{2} (1.1 \times 1 0^{- 4}) K_{s p} = (4.84 \times 1 0^{- 8}) (1.1 \times 1 0^{- 4}) = 5.324 \times 1 0^{- 12} .
