Which of the following is an incorrect statement?a)Temporary hardness ...
Incorrect Statement Explanation:
Temporary hardness of water is due to bicarbonates of Ca and Mg, not chlorides and sulphates. The presence of calcium and magnesium bicarbonates in water causes temporary hardness, as these ions can be removed by boiling. Boiling causes the bicarbonates to decompose into insoluble carbonates, which can then be easily removed.
Corrected Statements:
- Temporary hardness of water is due to bicarbonates of Ca and Mg, not chlorides and sulphates.
- Permanent hardness of water is due to chlorides and sulphates of Ca and Mg.
- Temporary hardness of water can be removed by boiling, as it causes the bicarbonates to decompose into insoluble carbonates.
