Question

Consider the redox reaction below.

Answer 1

Answer:

Fe2+ (aq) + 2e -> Fe(s)

Explanation:

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Consider the following reaction:

Mg(s) + Fe2+ (aq) —>Mg2+ (aq) + Fe(s)

Magnesium loses its two valance electrons and oxidized while iron accept two electrons get reduced.

Magnesium is reducing agent while iron is oxidizing agent.

Oxidizing agents:

Oxidizing agents oxidize the other elements and itself gets reduced.

Reducing agents:

Reducing agents reduced the other element are it self gets oxidized.
