REDOX REACTION
OXIDANT OR OXIDISING AGENT
As stated above the oxidising agent may be defined as a substance supplying oxygen or
electronegative element, removing hydrogen or electropositive element and can accept electrons. They
show decrease in oxidation number
Examples - K 2Cr 2O 7, KMnO 4, H 2O 2, Cl 2, Br 2, KClO 3, FeCl 3 etc.
REDUCTANT OR REDUCING AGENT
A substance supplying hydrogen or electropositive element, removing oxygen or electronegative
element and can donate electrons. They show increase in oxidation number.
Examples - SnCl 2, H 2, H 2S, Mg, FeSO 4, H 2C 2O 4, H 2SO 3.
