WebJan 24, 2024 · Example 5: Reaction between manganese dioxide and hydrogen chloride. In this reaction, manganese dioxide loses oxygen and thereby gets reduced to manganese chloride. Hence, it acts as an oxidising agent. On the other hand, hydrogen chloride gains oxygen, thereby reduced to water. WebWhat changes in this reaction is the oxidation state of these atoms. The oxidation state of carbon increases from +2 to +4, while the oxidation state of the hydrogen decreases from +1 to 0. Oxidation and reduction are therefore best defined as follows. Oxidation occurs when the oxidation number of an atom becomes larger.
