Question

Electrolysis of NaCl produces ( )
A) H2, Na2CO3 B) H2, Cl2, NaOH C) only NaOH D) NaHCO3​

Answer 1

ANSWER IS B

I THINK SO IT HELPS

Answer 2

Electrolysis of NaCl

Explanation:

During electrolysis of sodium chloride solution following reaction takes place;

    2NaCl(Aq) + 2$H_{2}O$ → $Cl_{2} + H_{2} + 2NaOH$         -------(overall reaction)

At Anode - chloride ion is oxidized to chlorine

 $Cl^{-}$ →  $\frac{1}{2}Cl_{2} + e^{-}$

At Cathode - water is reduced to hydroxide and hydrogen gas

$H_{2}O + 2e^{-}$ → $H_{2} + 2OH^{-}$

Hence, the correct option is (B)
