Carbonates
Practical Applications of Carbonates. Permanent hard water contains HCO 3-.By adding Na 2 CO 3 (washing soda), the water is softened and hard water precipitates calcium and magnesium. Ammonium sulfide group filtrate, when treated with CO 3 2-, yields precipitate from the fourth group (Mg, Ca, Sr, Ba). Aqueous carbonate anion is the key …Web

Carbonate Ion (CO₃²⁻)
Solubility. Carbonate ion can be precipitated from solution as white barium or calcium salts that have low solubilities: Although many carbonate salts are insoluble, those of Na +, K +, and NH 4 + are quite soluble. All bicarbonate ( HCO 3 −) salts are soluble. Because of this, even insoluble carbonate salts dissolve in acid.Web
