Converting Carbonate Alkalinity from mg/L as CaCO 3 to mg/L as CO 3 2-CaCO 3 has a molecular weight of 100 g/mol The CO 3 2-anion has a molecular weight of 60 g/mol Therefore, each milligram of CaCO 3 contains 60/100 = 0.6 mg of CO 3 2-The conversion is as follows: Carbonate Alkalinity as CO

a. Lime is produced by heating limestone in a kiln to change the mineral into calcium oxide, and calcium carbonate (aka: pulverized limestone or fine grind) is produced by pulverizing high-grade calcium minerals, in Pete Lien & Sons' case limestone, into a ground granular or power sized finished product.
