What is Redox reaction?

1 Answer


Redox reaction is when one reactant gets oxidised and another reactant gets reduced in the same reaction


A redox reaction is literally a RED uction- OX idation reaction where one reactant gets reduced and another gets oxidised.

There are a few ways to determine if a reactant is oxidised or reduced.

For oxidation :

  1. Gain in oxygen (for neutral species)
  2. Loss of hydrogen (for neutral species)
  3. Increase in oxidation state or oxidation number
  4. Loss of electrons

Conversely, for reduction :

  1. Loss of oxygen (for neutral species)
  2. Gain in hydrogen (for neutral species)
  3. Decrease in oxidation state or oxidation number
  4. Gain of electrons

Hope this helps!

Warmest regards!
