Question

The electrolysis of water involves a combination reaction.

• A. True
• B. False

Answer 1

The correct option is B False

The above statement is false because electrolysis of water(${\mathrm{H}}_2\mathrm{O}$) is the decomposition reaction of water into Hydrogen (${\mathrm{H}}_2$) and Oxygen (${\mathrm{O}}_2$) gas due to the passage of an electric current through the water.

Chemical equation :

$2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\rightleftharpoons 2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$
