Solution
Temporary hardness is water hardness due to the presence of calcium and magnesium carbonates and bicarbonates, which can be precipitated by heating the water. It can be removed by processes such as boiling or lime softening, and then separation of water from the resulting precipitate.
Temporary hardness is very common and is responsible for the deposition of calcium carbonate scale in pipes and equipment. These deposit formations lead to clogged plumbing and reduced efficiency of heat exchangers.
Temporary hardness is also known as carbonate hardness.
