which chemical is used to soften hard water?
489485
Water softening is achieved either by adding chemicals that form insoluble precipitates or by ion exchange. On a small scale, chemicals used for softening include ammonia, borax, calcium hydroxide (slaked lime), or trisodium phosphate, usually in conjunction with sodium carbonate (soda ash).

Permanent hardness is caused by dissolved calcium sulfate (which is not removed by boiling). Hard water contains dissolved magnesium and calcium ions. These make it more difficult for the water to form a lather with soap. Temporary hardness is caused by dissolved calcium hydrogencarbonate (which is removed by boiling).

Tetrasodium EDTA is used as a chelating agent, or to put it in layman's terms, it makes hard water become soft. As water makes its way through the water cycle, it sometimes picks up metal ions such as calcium and iron. These metal ions can make water hard, which is a problem because hard water won't get you clean.

Typically, water that contains less than 1 grain per gallon is considered soft, while water with 1 to 3.5 grains per gallon is slightly hard. Water in these two categories is, by most accounts, soft enough that it does not require further softening.
