Estimation of total, permanent and temporary hardness of ...
www.bsauniv.ac.inPage 2 of 6 2. Temporary hardness Temporary hardness is due to the presence of bicarbonates of calcium and magnesium ions. It can be easily removed by boiling. When water is boiled, temporary hardness producing substances (bicarbonates) are precipitated as insoluble carbonates or hydroxides. This precipitate can be removed by filtration.
