Calculate the solubility of Ag(2)CrO(4) ...

Calculate the solubility of `Ag_(2)CrO_(4)` in 0.1M `AgNO_(3)K_(sp)` of `Ag_(3)CrO_(4)=1xx10^(-22)`

Text Solution

Verified by Experts

`Ag_(2)CrO_(4)hArr2Ag^(+)+CrO_(2)^(2-)`
`2xx0.1+x`
`K_(sp)=[Ag^(+)]^(2)[CrO_(4)^(2-)]`
`1xx10^(-12)=(2xx0.1)^(2)[CrO_(4)^(2-)]`
`[CrO_(4)^(2-)]=(1xx10^(-12))/((2xx0.1)^(2))=(1xx10^(-12))/0.04=0.025xx10^(-10)`
