उत्तर १
An oxidising agent is a reactant which readily transfers oxygen atoms to another substance by reducing itself in the process.
उत्तर २
The substances which can give oxygen to other substances are called oxidant or oxidizing agents.
E.g. Potassium permanganate (KMnO4) and potassium dichromate (K2Cr2O7) in acidic or alkaline medium is commonly used oxidants.
