In an electrolytic cell hydroxide ions are combined to give _.
Correct answer: C. Oxygen
- A. Alcohols
- B. Aldehydes
- C. Oxygen
- D. Hydrogen
Explanation
The correct option is C. Hydroxide ions are combined to give oxygen to an electrolytic cell. When an electric current is passed through an aqueous solution of hydroxide ions, the hydroxide ions are discharged at the anode, where they combine to form oxygen gas. The equation for this reaction is: 4OH- → 2H2O + O2 The oxygen gas is then released from the cell. So the answer is oxygen.

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.
