Question:
What are the products formed in sequence when excess of $\mathrm{CO}_{2}$ is passed in slaked lime?
Correct Option: , 2
Solution:
$\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{CO}_{2} \longrightarrow \mathrm{CaCO}_{3} \downarrow+\mathrm{H}_{2} \mathrm{O}$
$\mathrm{CaCO}_{3} \downarrow+\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2}$
