The balanced oxidation half equation is given below:
Oxidation reactions are reactions in which the oxidation of the species increases.
Oxidation reactions can involve addition of oxygen or electronegative elements to a substance or the removal of hydrogen or electropositive elements from a substance.
The balanced half-reaction for the oxidation of solid manganese dioxide to permanganate ion in acidic aqueous solution is given below:
MnO₂ + H₂O → MnO₄⁻ + H⁺ + 3 e⁻
