A solution of `Na_(2)CO_(3)` is added drop by drop to 1 litre of a solution containing `10^(-4)` mole of `Ba^(2+)` and `10^(-5)` mole of `Ag^(+)`, if `K_(sp)` for `BaCO_(3)` is `8.1xx10^(-9)` and `K_(sp)` for `AgCO_(3)` is `6.9xx10^(-12)` then which is not true?A. No precipitate of `BaCO_(3)` will appear untill [`CO_(3)^(2-)`] reaches `8.1xx10^(-5)` mol per litre.B. A precipitate of `Ag_(2)CO_(3)` will appear when `[CO_(3)^(2-)]` reaches `6.9xx10^(-5)` mol per litre.C. No precipitate of `Ag_(2)CO_(3)` will appear untill `[CO_(3)^(-2)]` reaches `6.9xx10^(-2)` mole per litre.D. `BaCO_(3)` will be precipitate first. |
