When carbon dioxide is passed in excess it leads to the formation of calcium hydrogen-carbonate. 2. On a large scale, it is prepared by passing carbon dioxide gas through calcium hydroxide (slaked lime). However, if carbon dioxide is passed in excess, it forms the soluble calcium hydrogen-carbonate. Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O
