Question

State True or False.

Aqueous solution of brine on electrolysis forms sodium.

• A. True
• B. False

Answer 1

The correct option is B False

Sodium chloride dissolved in water is called brine. Electrolysis of brine gives hydrogen gas at the cathode and chlorine gas at the anode.
Reaction at anode:
$2C{l}^{-}\to C{l}_2+2e^{-}$
Reaction at cathode:
$N{a}^{+}+e\to Na$
$2Na+2H_{2}O\to 2NaOH+H_2$
