Interpretation:
The balanced equation has to be written for the oxidation of p-xylene to 1,4-benzenedicarboxylic acid using potassium dichromate in aqueous sulfuric acid, and milligrams required of
Concept introduction:
To balance half-reactions in Acidic conditions:
Balance oxidation number with electrons
Balance elements except oxygen and hydrogen.
Balance oxygen with water.
Balance H with
Balance net charge with electrons
Balance net equation with
Oxidation: Loss of electron
Reduction: Gain of electron
An oxidizing agent gains the electrons and is reduced in a
A reducing agent loses electrons and is oxidized in a chemical reaction and it is electron donor.
The oxidation state is called as oxidation number, which describes degree of oxidation (loss of electrons) of an atom in a chemical compound. Theoretically, the oxidation state is positive, negative or zero.
