Water Technology Hardness of Water: Natural waters containing large quantities of dissolved salts of Calcium (Ca) & Magnesium (Mg) is called hard water. It is a characteristic of preventing lather formation of water with soap. Ca2+ & Mg2+ ions react with soaps which are salts of fatty acids (stearic or palmitic acid) to give insoluble scums or precipitates of calcium or magnesium stearate or palmitate. 2C17H35COO- + Ca2+ → (C17H35COO)2 Ca (scum) 2C17H35COO- + Mg2+ → (C17H35COO)2
