Concentration of the Ag^(+) ions in a saturaed solution of Ag_(2)C_(2)O_(4) is 2.2 xx 10^(-4) mol L^(-1). Solubility product of Ag_(2)C_(2)O_(4) is :

Answer»

`2.66 xx 10^(-12)`
`4.5 xx 10^(-11)`
`5.3 xx 10^(-12)`
`2.42 xx 10^(-8)`

Solution :`Ag_(2)C_(2)O_(4) HARR 2Ag^(+) + C_(2)O_(4)^(2-)`
`2.2 xx 10^(-4)M 1.1 xx 10^(-4) M`
`K_(SP) = [Ag^(+)]^(2)[C_(2)O_(4)^(2-)]`
`= [2.2 xx 10^(-4)]^(2).[1.1 xx 10^(-4)]`
`K_(sp) = 5.3 xx 10^(-12)`.
