What is Magnesium Bicarbonate?
Magnesium Bicarbonate is an unstable compound of magnesium in solid state with the formula Mg(HCO3)2, it exists only in solutions. It exists only in solution and is formed by the action of water containing free carbon dioxide on magnesite, dolomite, dolomitic limestone and other minerals containing magnesium carbonate. It causes temporary hardness in water and on heating it easily decomposes back to carbonate.
IUPAC name – Magnesium hydrogen carbonate
