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

Answer»

Solution :`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)`
