Question

All of the following are oxidation, except
Increase in oxidation state
Loss of electrons
Gain of oxygen
Loss of proton​

Answer 1

Answer:

Correct option is

D

All the above statements are correct

Oxidation reaction is a type of chemical reaction in which there is removal electron, removal of hydrogen and some time there is a loss of electropositive radicals takes place. Hence, option D is correct.

Answer 2

Option D) Loss of Proton

Explanation:

• Oxidation is the process by which a substance is affected by oxygen. It is what causes rust to develop. This process can be controlled, but often is not.
• Oxidation occurs at many places including the air, water, soil and on the surfaces of things.

• Oxidation is the process where metal or an alloy oxidizes or reacts with oxygen.
• An electrochemical process, caused by a reaction between a metal and an oxidant, resulting in the loss of electrons, and the formation of compounds with a high positive charge such as rust. The electrons are released to the external circuit by an electric current. In this way, the oxidation is irreversible and the metal loses its original properties.
