-Most of the sulphates are soluble.
- and are sparingly soluble.
- are insoluble sulphates.
-Except alkali metal sulphates, all other metal sulphates are thermally unstable.
i) Passing through Alkali:
ii) By heating Bicarbonates:
iii) By fusion with Sodium Carbonate:
iv) By Double Decomposition:
-Alkali metal carbonates are soluble in water except
-Alkali metal carbonates are thermally stable except which is thermally unstable.
-Other metal carbonates are thermally unstable.
