Question

Give 3 example of reduction

Answer 1

Examples of Reduction Reactions

Gain of electrons resulting in decrease in positive charge

Fe3+ + e- → Fe2+

Iron (III) ion gains one electron and changes to Iron (II) ion, and hence gets reduced.

Sn4+ + 2e-→ Sn2+

Tin (IV) gets reduced to tin (ii) ion, with the addition of electrons.

Gain of electrons resulting in increase in negative charge

MnO4-+ e-→ MnO4 2-

With the gain of electrons, MnO4- is reduced to MnO4 2-.

With the increase in negative charge, the oxidation number is decreased.
