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.Calcium carbonate is the active ingredient in agricultural lime and

Carbonate chemistry — Science Learning Hub

Calcium carbonate has a very low solubility in pure water (15 mg/L at 25°C), but in rainwater saturated with carbon dioxide, its solubility increases due to the formation of more soluble calcium bicarbonate. Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases.

(a) Calcium reacts with cold water to form calcium hydroxide along with evolution of hydrogen gas. (b) The piece of calcium metal starts floating in water because the bubbles of hydrogen gas formed during the reaction stick to its surface.

AS Chemistry - Redox Reactions and Group 2 …

A redox reaction is a reaction that involves both oxidation (the loss of electrons) and reduction (the gain of electrons). In order to identify whether a reaction is redox or not, you can write separate half equations that show how electrons are lost/gained. For example, take the equation for the reaction of Calcium and Oxygen:. 2Ca (g) + O 2 (g) -> 2CaO (s),
