Calcium oxide (CaO) i.e., quick lime is a drying agent and can react with$\mathrm{C}{\mathrm{O}}_2$and water vapours as follows
$\mathrm{C}\mathrm{a}\mathrm{O}+\mathrm{C}{\mathrm{O}}_2\to \mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{O}}_3$
$\mathrm{C}\mathrm{a}\mathrm{O}+{\mathrm{H}}_2\mathrm{O}\to \mathrm{C}\mathrm{a}(\mathrm{O}\mathrm{H}{)}_2$
