Answer: option iii)
Ca(OH)2 is the chemical A that is used in the manufacturing of washing soda Na2CO3 in order to recover ammonia. It is a reaction that occurs during the Solvay process, which is used to produce sodium carbonate.
A chemical A is used for the preparation of washing soda to recover ammonia. When CO2 is bubbled through an aqueous solution of A, the solution turns milky. It is used in whitewashing due to disinfectant nature. What is the the chemical formula of A? (i) Ca (HCO3)2 (ii) Cao (iii) Ca(OH)2 (iv) CaCO3
