Vedclass · Answer

(C) In the Solvay process,$Ca(OH)_2$ is used to recover $NH_3$ from $NH_4Cl$ as follows: $2NH_4Cl + Ca(OH)_2 \rightarrow 2NH_3 + CaCl_2 + 2H_2O$. When $CO_2$ is passed through an aqueous solution of $Ca(OH)_2$ (lime water),it turns milky due to the formation of insoluble $CaCO_3$: $Ca(OH)_2 + CO_2 \rightarrow CaCO_3 \downarrow + H_2O$. $Ca(OH)_2$ is also used in whitewashing because of its disinfectant properties. Therefore,the compound $(A)$ is calcium hydroxide,$Ca(OH)_2$.

$A$ compound $(A)$ is used in the preparation of washing soda to recover ammonia in the Solvay process. When $CO_2$ is bubbled through an aqueous solution of $(A)$,the solution turns milky. It is used in whitewashing due to its disinfectant nature. What is the chemical formula of $(A)$?
