Question

During the electrolysis of aqueous sodium chloride the cathodic reaction is (A) Oxidation of Cl- ion (B) Oxidation of Na+ ion (C) Reduction of H2O (D) Oxidation of H2O

Tardigrade Admin · Accepted Answer

2H+ + 2e- arrow H2 H+ undergo reduction in preference to Na+ because of greater reduction potential

Q. During the electrolysis of aqueous sodium chloride the cathodic reaction is

Oxidation of $C l^{-}$ ion

Oxidation of $N a^{+}$ ion

Reduction of $H_{2} O$

Oxidation of $H_{2} O$

$2 H^{+} + 2 e^{-} \to H_{2}$
$H^{+}$ undergo reduction in preference to
$N a^{+}$ because of greater reduction potential

Q. During the electrolysis of aqueous sodium chloride the cathodic reaction is

Oxidation of Cl− ion

Oxidation of Na+ ion

Reduction of H2​O

Oxidation of H2​O

2H++2e−→H2​ H+ undergo reduction in preference to Na+ because of greater reduction potential
