Question

The oxidation reaction among the following is:

Options

• \[\ce{Fe^{3+} + 3e- -> Fe}\]

• \[\ce{Fe^{2+} - 1e- -> Fe^{3+}}\]

• \[\ce{Cl2 + 2e- -> 2Cl-}\]

• \[\ce{Cu^{2+} + 2e- -> Cu}\]

Answer 1

\[\ce{Fe^{2+} - 1e- -> Fe^{3+}}\]

Explanation:

According to the electronic concept, oxidation is defined as a chemical process that involves the loss of electrons. In this reaction, a ferrous ion (Fe²⁺) loses one electron to form a ferric ion (Fe³⁺).
