What happens in redox reactions?

Question

Quizplus · Accepted Answer

Redox reactions involve both the transfer of electrons (electron exchange) and the breaking down of molecules (decomposition). This can result in either oxidation (loss of electrons) or reduction (gain of electrons) of the reactants involved. Therefore, choice A is the correct option.

Answer: B
 In a redox reaction, the electron acceptor is reduced (gains electrons) while the electron donor is oxidized (loses electrons). Therefore, choice B is an incorrect option and should be eliminated.

Answer: C
 Redox reactions involve the transfer of electrons from one reactant to another. The reactant that loses hydrogen is usually oxidized (loses electrons), while the reactant that gains hydrogen is usually reduced (gains electrons). Therefore, choice C is an incorrect option and should be eliminated.

Answer: D
 Redox reactions can occur in both directions - forward and backward - depending on the conditions of the reaction. Therefore, the reaction is not uniformly reversible, and choice D is an incorrect option and should be eliminated.
