Question

Complete the following reaction:

${\mathrm{H}}_2\mathrm{O}\stackrel{\mathrm{electricity}}{\to }$

Answer 1

Electrolytic decomposition:

• Some reactions occur when an electric discharge is passed.
• For example, acidulated water(${\mathrm{H}}_2\mathrm{O}$) decomposes by passing an electric current resulting in the formation of hydrogen($\mathrm{H}$) and oxygen($\mathrm{O}$) gases.
• $\underset{\mathrm{water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)}\stackrel{\mathrm{electricity}}{\to }\underset{\mathrm{hydrogen}\mathrm{gas}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{oxygen}\mathrm{gas}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}$
