Question

Quick lime ($CaO$) is an extremely important industrial chemical. Which of the following statements concerning its chemical behavior are correct?

Answer: A,B,C

💡 Solution & Explanation

Quick lime ($CaO$) slakes exothermically with water to form $Ca(OH)_2$. It acts as a basic flux in metallurgy, reacting with $SiO_2$ to form $CaSiO_3$ (slag). It safely dries basic gases like $NH_3$. However, it cannot be used to dry acidic gases like $HCl$ because it will undergo an acid-base reaction to form $CaCl_2$.
