Question

When current is passed through calculated water , the Hydrogen and Oxygen separates . The hydrogen gets accumulated on the negative electrode . Why does it not deposit on positive electrode?

• A. Hydrogen is positive charge
• B. Hydrogen is negatively charged
• C. That is because , it is the characteristic of acidulated water
• D. None of the above

Answer 1

The correct option is A Hydrogen is positive charge

In a molecule of water, there are two hydrogen atom and one oxygen atom,i.e

$H_{2}O\to$ and Oxygen is an electronegative element,i.e which require a positive charge. While Hydrogen is an electropositive element, i.e which require negative charge or it has positive charge.

$⟹H_{2}O\to 2H^{+}+O^{-2}$ {After passing current it ionize and form ion}.

$\therefore$ As hydrogen has positive charge it will seek towards the negative elctrode.
