1.	Unlike sodium carbonate , potassium carbonate cannot be prepared by Solvay ammonia process . Why is it so ?
Answer» Solution :The reason being that unlike sodium bicarbonate `(NaHCO_(3))` which is SPARINGLY soluble in water , potassium bicarbonate `(KHCO_(3))` is FAIRLY soluble in water . Thus , when `CO_(2)` is passed through AMMONICAL brine , `NaHCO_(3)` gets precipitated while `KHCO_(3)` does not precipitated when `CO_(2)` is passed through and ammoniacal solution of KCL . Hence , `K_(2)CO_(3)` cannot be prepared by Solvay-ammonia process .
