Question

2NaCl(aq) + 2H2O(l) ---->2NaOH(aq) + Cl2(g) + H2(g)
Which type of reaction is it ?
other answer then electrolysis

​

Answer 1

Answer: This reaction is also known as Reduction reaction.

Answer 2

Answer:

The given reaction is type of chloro-alkali process.

Explanation:

Chloro-alkali process is employed for the formation of $NaOH$ on the industrial scale.

• For the preparation of $NaOH$, in this process the electricity transferred through the salty water.
• When electricity passes through the aqueous solution of $NaCl$. It brakes into $NaOH$ and releases $Cl_{2}$ and $H_{2}$ gas along with it.

  At anode:          $2Cl^{-}+2e^{-}$  →   $Cl_{2}$

 At cathode:        $2H_{2}O+2e^{-}$   →   $H_{2}+2OH^{-}$

The overall reaction:

                 $2NaCl(aq) + 2H_{2}O(l)$   →   $2NaOH(aq) + Cl_{2}(g) + H_{2}(g)$
