At `20^(@)C`, the `Ag^(+)` ion concentration in a saturated solution `Ag_(2)CrO_(4)` is `1.5 x10^(-4)` mol `//` litre. At `20^(@)C`, the solubility product of `Ag_(2)CrO_(4)` would be

Text Solution

Verified by Experts

`Ag_(2)CrO_(4) hArr 2Ag^(+) + CrO_(4)^(2-)`
`K_("sp") = [Ag^(+)]^(2) [CrO_(4)^(2-)] = (1.5 xx 10^(-4))^(2) (0.75 xx 10^(-4)) = 1.6875 xx 10^(-12)`
