Question

When current is passed through tap 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

Opposite charged ends attract to each other. In $H_{2}O$, the hydrogen is positive charged, therefore it is attracted to negatively charged electrodes, whereas Oxygen being negatively charged ion , gets attracted to positive electrode.
