1.	At times warming is suggested while precipitating group V cation explain.
Answer» Solution :The IMPURITY of bicarbonate ion in `(NH_(4))_(2)CO_(3)` fomrs decomposes these bircarbonates into normal carbonates which are precipitated `Ca(HNO_(3))_(2)toCaCO_(3)+H_(2)O+CO_(2)` the solution MUST not be boiled otherwise insoluble carbonates with ammonium chloride are converted into soluble chlorides.
