A chemical A is used for the preparation of washing soda to recover ammonia. When CO_{2} is bubbled through an aqueous solution of A, the solution turns milky. It is used in white washing due to its disinfectant nature. What is the chemical formula of A?
(i) Ca (HCO_{3})_{2}
(ii) CaO
(iii) Ca(OH)_{2}
(iv) CaCO_{3}

Answers (1)

The answer is option (iii).

On passing CO_{2} through Ca(OH)_{2}, lime water, turns from colourless to milky due to the formation of CaCO_{3}.

Ca(OH)_{2}+CO_{2}\rightarrow CaCO_{3}+H_{2}O

Also in Solvay Ammonia soda process,
2NH_{4}Cl+Ca(OH)_{2} \rightarrow 2NH_{3}+2H_{2}O+CaCl_{2}
