Study the given figure carefully, which represents the decomposition of aqueous sodium chloride solution by passing electricity.
Identify the X, Y, P, Q and R in the below figure.
Hint:
NaCl(aq) 
NaOH + H2 + Cl2
The correct answer is:
In decomposition of aqueous sodium chloride solution by passing electricity:
NaCl(aq) NaOH + H2 + Cl2
Chlorine is oxidised and released as chlorine gas at anode.
Hydrogen is reduced and released as hydrogen gas at cathode.
X is cathode, Y is anode, P is hydrogen gas, Q is chlorine gas and R is NaOH.
