Solution

## Reaction of slaked lime $\left(\mathrm{Ca}{\left(\mathrm{OH}\right)}_{2}\right)$ with carbon dioxide:“Calcium hydroxide reacts slowly with the carbon dioxide in the air to form a thin layer of calcium carbonate on the walls.”When Calcium hydroxide $\left(\mathrm{Ca}{\left(\mathrm{OH}\right)}_{2}\right)$ reacts with carbon dioxide $\left({\mathrm{CO}}_{2}\right)$, Calcium carbonate $\left({\mathrm{CaCO}}_{3}\right)$ is formed along with water $\left({\mathrm{H}}_{2}\mathrm{O}\right)$.The chemical equation can be depicted as:$\mathrm{Ca}{\left(\mathrm{OH}\right)}_{2}\left(\mathrm{aq}\right)+{\mathrm{CO}}_{2}\left(\mathrm{g}\right)\to {\mathrm{CaCO}}_{3}\left(\mathrm{s}\right)+{\mathrm{H}}_{2}\mathrm{O}\left(\mathrm{l}\right)$Uses of slaked lime:In sewage systems, slaked lime is used as a flocculant.Slaked lime has wide applications in the food industry.
