Sodium chromate solution is gradually added to a mixture containing `0.05 M Pb^(2+)` ions and `0.10 M Ba^(2+)` ions. The concentration of the ion precipitating first when the second ion begins to form a percipitate is [Note: `K_(sp)` of `BaCrO_(4)=2.4xx10^(-10)` and `K_(sp)` of `PbCrO_(4)=1.8xx10^(-14)`]
