Define oxidising and reducing agents in terms of electrons

Text Solution

Verified by Experts

oxidising agents are electron acceptors while reducing agents are electron donor for exaple
oxidising agent : `MnO_(4)^(-) + 8H^(+)+5e^(-)rarrMn^(2+)+4H_(2)O`
Reducing agent : `Fe^(2+) rarr Fe^(3+)+e^(-)`
