Vedclass · Answer

(A) Calcium oxide $(CaO)$,also known as quicklime,is a basic oxide. It reacts with water vapor to form calcium hydroxide: $CaO + H_2O \rightarrow Ca(OH)_2$. It also reacts with acidic gases like $CO_2$ to form calcium carbonate: $CaO + CO_2 \rightarrow CaCO_3$. Therefore,it acts as a drying agent that can remove both water vapor and carbon dioxide.

Which of the following is a drying agent that reacts with $CO_2$ and removes water vapor?
