Question

How can you identify a redox reaction?

Answer 1

ANSWER:

B. Electrons have transferred from one atom to another.

EXPLANATION:

An oxidation-reduction (redox) reaction is a reaction which involves the change in oxidation number of the atoms involved. Since the oxidation number changes, this means that one atom has to lose electrons and another has to accept electrons. The reactant that loses electrons is called REDUCING AGENT while the reactant that gains electrons is called OXIDIZING AGENT.

For example, in a reaction between iron and oxygen as follows:

4Fe+ 3O2→2Fe2O3

Iron is reduced from +2 to 0 because it accepts electrons from oxygen while oxygen is oxidized from -2 to 0 because it transfers electrons to iron.

Hence, a redox reaction can be identified by the transfer of electrons from one atom to another.
