Question

Chemical reactions that need energy in the form of electricity to take place are called electrochemical reactions.

• A. True
• B. False

Answer 1

The correct option is A True

• Many chemical reactions need energy in the form of electricity to take place. They are called electrochemical reactions.
• Example- On passing an electric current through acidified water, hydrogen and oxygen are produced.

$\underset{\mathrm{Acidified}}{2{\mathrm{H}}_2\mathrm{O}}\stackrel{\mathrm{Electric}\mathrm{curent}}{\to }\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2}$
