Question

When electricity is passed through acidified water, it decomposes to give hydrogen and carbon dioxide.

• A. True
• B. False

Answer 1

The correct option is B False

Decomposition of water -

• Decomposition reactions that take place when an electric current is passed through the compound in its molten state or in its aqueous solution are called electrolysis decomposition reactions or electrolysis.
• When electricity is passed through acidified water, it decomposes to give hydrogen and oxygen.

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

Therefore, the given statement is false.
