2020/7/7· The water alkalinity in these water bodies, in connection with the initial pH < 7.0, was too small to compensate for the changes caused by the use of a strongly acidic preparation material. These results correspond well with those in previous reports by Klapper ( 2003 ), who reported limit-safe doses of aluminum sulfate at the level of 3 g Al/m 3 for every 10 mg/L of CaO in terms of the water

Chalk is almost pure calcium carbonate. We can work out its purity by measuring how much carbon dioxide is given off. 10 g of chalk was reacted with an excess of dilute hydrochloric acid. 2.128 liters of carbon dioxide gas was collected at standard temperature
Calcium carbonate - Wikipedia
Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs., and eggs.
