Carbonatation

Carbonatation is a chemical reaction in which calcium hydroxide reacts with carbon dioxide and forms insoluble calcium carbonate:

${\displaystyle {\ce {Ca(OH)2{+}CO2->CaCO3{+}H_2O}}}$

The process of forming a carbonate is sometimes referred to as "carbonation", although this term usually refers to the process of dissolving carbon dioxide in water.
