Acid, Injection: Mineral ,acid,, such as sulfuric or hydrochloric, neutralizes carbonate alkalinity resulting in a decrease in pH. Reducing the carbonate alkalinity increases the solubility of calcium salts such as calcium carbonate by preventing the formation of carbonate (CO3) alkalinity and its subsequent reaction with calcium hardness to form lime scale.
