Can steel be oxidized

WebThe method is based on the dissolution of the steel in nitric acid which also oxidizes the Mn to Mn 2+. The reaction involved is: 3Mn + 2NO − 3 + 8H + ⇌ 3Mn2 + + 2NO + 4H 2O The nitric oxide produced must be removed since it would react with periodate and would thus inhibit the oxidation of the Mn 2+ to permanganate.
