    Which of the following is a temporary hardness causing

    Feb 02, 2021 Water hardness is due to the presence of di- cations including Ca2 and Mg2. Temporary hardness is mainly caused by the carbonates and bicarbonates of calcium and magnesium. It can be easily removed by boiling of water. Permanent hardness is due to presence of sulfates and chlorides of calcium and magnesium in water.
