Potassium permanganate sulfuric acid (A) as a laboratory chemical is mainly used as an oxidizing agent in a variety of laboratory applications. Its suitability is particularly evident in organic chemistry, in the determination of oxidation states or as a cleaning solution.

The chemical and physical processes involved in using the solution lie in the strong oxidizing property of potassium permanganate. In combination with the sulfuric acid, a strong oxidation medium is formed. In this process, potassium permanganate is protonated by the sulfuric acid, which leads to an increased oxidizing ability.

The application of this solution can lead to different results, depending on the specific reaction. It is possible to oxidize reducible substances, determine oxidation states, or eliminate organic residues. The exact effect varies depending on the context and substances used, giving the solution a wide range of possibilities in laboratory applications.
