4.1.4 Oxidation and reduction in terms of electrons (HT only)

What is oxidation in terms of electrons?

A

In the reaction

Fe(s)+CuSO4(aq)→FeSO4(aq)+Cu(s) \text{Fe}(s) + \text{CuSO}_4(aq) \rightarrow \text{FeSO}_4(aq) + \text{Cu}(s) Fe(s)+CuSO4​(aq)→FeSO4​(aq)+Cu(s)

, the Cu2+\text{Cu}^{2+}Cu2+ ions become copper atoms, so the copper ions are reduced.

B

It splits into separate aqueous ions.

C

Loss of electrons.

D

Electrons on the left of a half equation show that the species is reduced.
