Which of the following occurs in an oxidation reaction?
A.
Removal of oxygen
B.
Addition of carbon
C.
Addition of neutrons
D.
Removal of electrons
The correct answer is:
D. Removal of electrons
Explanation: Oxidation is defined as the process in which an atom, ion, or molecule loses electrons. It is one half of a redox (reduction-oxidation) reaction, where the other half involves the gain of electrons (reduction). In oxidation reactions, the removal of electrons increases the oxidation state of the substance.
- A. Removal of oxygen is not accurate as oxidation can occur with or without oxygen.
- B. Addition of carbon is not a characteristic of oxidation.
- C. Addition of neutrons is not related to oxidation reactions.
