Question

Define electrochemical reaction.

Answer 1

• Electrochemical reaction - A reaction that takes place when the electricity is passed through the reactants. Such reactions are called electrochemical reactions.
• Example - Water dissociates into hydrogen and oxygen on passing electricity through it.

$\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\stackrel{\mathrm{electricity}}{\to }\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}$
