At 25^(@) temperature, the solubility products for BaCrO_4 and SrCrO_4 salts are 2.4xx10^(-10) and 3.6xx10^(-6) respectively. If an aqueous solution of K_2CrO_4 is added drop by drop to an aqueous solution containing Ba^(2+) and Sr^(2+) ions with concentrations of 10^(-4) and 10^(-3)(M) respectively then-

Answer»

`BaCrO_4` will be precipitated first
`SrCrO_4` will be precipitated first
the concentration of `SR^(2+)` IONS will be `6.6xx10^(-8)MOL*L^(-1)` when `Sr^(2+)` ions start precipitating
the concentration of `BA^(2+)` ions will be `6.6xx10^(-8)mol*L^(-1)` when `Sr^(2+)` ions that precipitating
