Redox reaction

Nonredox reactions

Definition

Is a chemical process where electrons are transferred between two substances (oxidation and reduction occur simultaneously)

Non-redox reactions are chemical reactions in which there is no change in the oxidation states of the involved elements

Electron transfer

Present

Not present

Oxidation state

Changes in the oxidation states of elements occur

Oxidation states of elements remain unchanged

Redox pair 

Involves redox pairs: oxidizing agent (accepts electrons) and reducing agent (donates electrons)

No redox pairs involved
