Question

How do electrons participate in half reactions?

Answer 1

Answer:

Oxidation-Reduction Reactions. Redox reactions are comprised of two parts, a reduced half and an oxidized half, that always occur together. The reduced half gains electrons and the oxidation number decreases, while the oxidized half loses electrons and the oxidation number increases.

Explanation:

The electrons appear on the reactants side (left side) of a reduction half-reaction. The reductant is the reactant that is oxidized; it provides the electrons that are gained by the substance being reduced.

Answer 2

Answer:

a half reaction is either the oxidation and reduction reaction component of redox reaction is obtained by considering the change in oxidation states of individual substance involved in the redox reaction
