Some water is called ''hard'' water because, of all the deposits in the water.
magnesium and calcium.
In the United States mineral water is defined as water containing about 250 parts per million of dissolved solids. The dissolved solids are just calcium and magnesium ions.
Mg(C17H35COO)2 is formed, which is not water soluble. This is why detergents are often used instead of soaps in water containing magnesium or calcium ions - because no solids will form.
Presence of bicarbonates of chlorides or sulphates of calcium or magnesium in water are the main causes of hardness of water.
Such water is called "Hard".
Hard water is a mixture: water containing calcium and magnesium carbonates, also some sulfates or chlorides.
Water containing salts of calcium and magnesium as chlorides, sulfates, nitates - impossible to delete by boiling.
The amount of calcium and magnesium in water determines its hardness.

magnesium and calcium.
Reducing calcium and magnesium in the water is known as water softening. A water softener uses a carbon filtration system.
Tap water may contain: magnesium and calcium sulfates or magnesium and calcium carbonateswhilstsea water contains NaCl - salt
Clacium + Magnesium=> Carbon Dioxide + Water
Hydrogen gas is released when calcium and water react.
