What is oxidising agent and reducing agent explain with examples . Please explain me so that I can solve any question regarding it
An oxidizing agent is a substance that oxidizes other chemical substance and reduces itself. Oxidising agents give oxygen to or removes hydrogen from other substances.
The reducing agent undergoes loss of electrons. A reducing agent (also called a reductant or reducer) is an element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized.
eg:3MnO2+4Al→3Mn+2Al2O3
Reducing agent: Al
Oxidation Agent: MnO2
