Question

Which of the following statement is true about the oxidation process?

• A. Loss of electron
• B. Addition of oxygen
• C. Addition of hydrogen
• D. All of the above

Answer 1

The correct option is D

All of the above

Explanation for correct option:

D. All of the above

Oxidation:

• Oxidation is a process that involves the loss of electrons.
• Oxidation can also be defined as the process that involves the addition of oxygen or the removal of hydrogen.
• An example of an oxidation reaction is depicted below:

$\mathrm{CuO}\left(\mathrm{s}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)\to \mathrm{Cu}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

• In this reaction, oxygen is added to Hydrogen producing a water molecule. Thus oxidation takes place while in the case of Copper, oxygen is being removed thus reduction is taking place.

Explanation for incorrect options:

All the given options are correct. Thus options A, B, and C are incorrect.

Hence, the correct option is D i.e. All of the above.
