Question

What happens when a concentrated solution of
sodium chloride is electrolysed? Write the
equation of the reaction involved.​

Answer 1

Answer:

When a concentrated solution of sodium chloride is electrolysed, it decomposes to form sodium hydroxide, chlorine and hydrogen

Chlorine gas is formed at anode (positively charged) and hydrogen gas at cathode (negatively charged)

The reaction takes place is given as:

2NaCl + 2H2O → 2NaOH + Cl2 + H2
