A compound $$(A)$$ is used in preparation of washing soda to recover ammonia in Solvay's process. When $$C{O_2}$$ is bubbled through an aqueous solution of $$(A),$$ the solution turns milky. It is used in white washing due to disinfectant nature. What is the chemical formula of $$A?$$

Question

A compound $$(A)$$ is used in preparation of washing soda to recover ammonia in Solvay's process. When $$C{O_2}$$ is bubbled through an aqueous solution of $$(A),$$ the solution turns milky. It is used in white washing due to disinfectant nature. What is the chemical formula of $$A?$$

A. $$Ca{\left( {HC{O_3}} \right)_2}$$

B. $$CaO$$

C. $$Ca{\left( {OH} \right)_2}$$

D. $$CaC{O_3}$$

Answer : $$Ca{\left( {OH} \right)_2}$$

Solution :
\[N{{H}_{3}}\uparrow \xrightarrow[\begin{smallmatrix} \text{Solvay }\!\!'\!\!\text{ s} \\ \text{process} \end{smallmatrix}]{N{{H}_{4}}Cl}\underset{\left( A \right)}{\mathop{Ca{{\left( OH \right)}_{2}}}}\,\xrightarrow{C{{O}_{2}}}CaC{{O}_{3}}\]
