A » Temporary hardness in water is caused by dissolved bicarbonate minerals that can be removed by boiling, leading to precipitated solids. In contrast, permanent hardness results from non-bicarbonate salts, such as chlorides and sulfates, which do not precipitate upon boiling and require chemical treatment for removal. Both types affect water quality, influencing its suitability for domestic and industrial use.

A »Temporary hardness is caused by dissolved bicarbonates of calcium and magnesium, which can be removed by boiling. Permanent hardness is due to other salts like sulfates and chlorides, requiring chemical treatment or ion exchange for removal.
