Calcium and Magnesium Oxide functions a pH adjusters. If you add enough water (or use a very small amount of calcium oxide), a colourless solution of calcium hydroxide is formed with a pH around 12. Calcium - Calcium - Compounds: The most important calcium compound is calcium carbonate, CaCO3, the major constituent of limestone, marble, chalk, oyster shells, and corals. This is due to Calcium being oxidation state +2 and Oxygen oxidation state is -2, this means when formed in a compound they cancel each other out to give CaO. cmg@nanoshel.com .
