Oxidation and Reduction processes

Oxidation

Oxidation is the process in which substance loses electrons.

​

For example:

Ca⁰ - 2e → Ca²⁺​

Oxidation and Reduction processes

Reduction

Reduction is the process in which substance gains electrons.

​

For example:

S⁰ + 2e → S^2-​

Gain electrons - reduction

GER

Lose electrons - oxidation

Oxidation and Reduction processes

What are the redox reactions?

Redox reactions primarily involve the transfer of electrons between two chemical species.

​

​In redox reactions, oxidation and reduction processes take place simultaneously.
