Question

A sample supposed to be pure `CaCO_(3)` is used to standardise a solution of `HCl`. The substance really was a mixture of `MgCO_(3)` and `BaCO_(3)`, but the standardisation of `HCl` was accurate. Find the percentage of `BaCO_(3)` and `MgCO_(3)` in mixture.

Answer 1

Correct Answer - `BaCO_(3)=27.89%, MgCO_(3)=72.11%`;
