When electricity is passed through water in the presence of an acid, oxygen and _ are produced.
Correct answer: D. Hydrogen
- A. Carbon
- B. CO
- C. CO2
- D. Hydrogen
Explanation
When electric current is passed through water, water dissociates into hydrogen and oxygen. Hydrogen is deposited over the negative pole and oxygen is deposited over the positive pole. Deposition of hydrogen and oxygen at different poles is visible in the form of bubbles.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
