Question

A metal oxide P reacts with water and forms a metal hydroxide Q. On the other hand, a gas R is obtained at a anode during the electrolysis of brine . Now, when R is passed over dry Q it gives compound S which is used for disinfecting drinking water. a) Identify P,Q,R,S. Write the chemical equations involved. b) Name the process used in the formation of R and write two uses of R.

Answer 1

Explanation:

Here,

X is calcium carbonate (CaCO3).

Y is slaked lime.

Z is bleaching powder (CaOCl2)

G is chlorine gas.

Hence the reactions are involved,
