Calcium and water formula
WebThe formula for lime water is Ca(OH) 2 and the chemical name for lime water is calcium hydroxide. When water is added to lime calcium hydroxide Ca(OH) 2 is formed … WebCalcium bicarbonate, also called calcium hydrogencarbonate, has the chemical formula Ca (HCO 3) 2. The term does not refer to a known solid compound; it exists only in aqueous solution containing calcium (Ca 2+ ), bicarbonate ( HCO− 3 ), and carbonate ( CO2− 3) ions, together with dissolved carbon dioxide (CO 2 ).
