Define solubility product. Write solubility product expressiions for the following:
`Ag_(2)Cr_(2)O_(7)`

Explanation

Solubility product: The procduct of the concentrations of a cation and anion in a saturated solution of a salt at room termperature, is called solubility product.
Solubility product for `Ag_(2)CrO_(4)`
`underset(S)(Ag_(2)CrO_(4))(s)hArr underset(2S)(2Ag^(+))+underset (S)(CrO_(4)^(2-))`
The solubility of `Ag_(2)CrO_(4)` is s moles `"lit"^(-1)`
`Ksp=[Ag^(+)]^(2)[CrO_(4)^(2-)]`
`=[2s]^(2)[s]=4s^(3)`
