Permanganic acid (HMnO₄) is a strong acid that contains the permanganate ion (MnO₄⁻). It is a powerful oxidizing agent, typically found in solution form, though it is relatively unstable and not commonly isolated in pure form. In aqueous solutions, it appears as a deep purple color due to the presence of the permanganate ion. Permanganic acid and its salts, such as potassium permanganate (KMnO₄), are widely used in analytical chemistry, disinfection, and organic synthesis. As an oxidizer, it is effective in redox reactions, particularly in oxidizing organic compounds and in environmental and industrial applications like water treatment.
