Many industrial and domestic water users are concerned about the hardness of their
water. Hardness is caused by compounds of calcium and magnesium and by a variety of
other metals. High levels of hard-water ions such as Ca
deposits in plumbing, appliances, and boilers. Water is an excellent solvent and readily
dissolves minerals it comes in contact with. As water moves through soil and rock, it
dissolves very small amounts of minerals and holds them in solution. Calcium and
magnesium dissolved in water are the two most common minerals that make water "hard".
Originally, the hardness of water was understood to be a measure of the capacity of water
for precipitating soap. Soap is precipitated chiefly by the calcium and magnesium ions
commonly present in water, but may also be precipitated by ions of other polyvalent
