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
plz give me ans

X is Calcium carbonate (CaCO3).
X is Calcium carbonate (CaCO3).CaCO3 + Acid = Metal Salt + Water + CO2
X is Calcium carbonate (CaCO3).CaCO3 + Acid = Metal Salt + Water + CO2If we take the acid as HCl then the reaction would be:
X is Calcium carbonate (CaCO3).CaCO3 + Acid = Metal Salt + Water + CO2If we take the acid as HCl then the reaction would be:CaCO3 + 2HCl -------> CaCl2 + CO2 + H2O
X is Calcium carbonate (CaCO3).CaCO3 + Acid = Metal Salt + Water + CO2If we take the acid as HCl then the reaction would be:CaCO3 + 2HCl -------> CaCl2 + CO2 + H2OY is Lime water Ca(OH)2 or slaked lime.When this CO2 gas is passed through Lime water , the lime water turns milky due to the formation of Calcium Carbonate and thus it is formed again.
