Solution
Conversion of ethanol to ethanoic acid is an oxidation reaction because oxygen is added to ethanol to convert it to ethanoic acid.
\[\ce{CH3 - CH2OH->[Alkaline KMnO4 + Heat][Or acidifted K2Cr2O7 + Heat] CH3COOH}\]
In the above reaction, alk. KMnO4/acidified K2Cr2O7 add oxygen to ethanol, hence they are called oxidising agents.
