A solutioncontains 0.1 MCl^(-)and 0.001MCrO_(4)^(2-). If solidAgNO_(3)is graduallyaddedto thissolutionwhich willprecipitatefirst, AgClor Ag_(2)CrO_(4) ? Assumethat the additioncauses no . Changein volume . GivenK_(ap(AgCl)) = 1.7 xx 10^(10) M^(2)and K_(ap(Ag_(2)CrO_(4))) = 1.79 xx10^(-12) M^(3). What %ofCl^(-)remainsin solution when CrO_(4)^(2-)startsprecipitating?
