The potassium dichromate-sulfuric acid solution is mainly used in analytical chemistry and histological staining. Its special suitability lies in the oxidation of organic substances, which is used in numerous analytical methods. In histology in particular, the solution enables specific staining of certain cell components and tissue types.

Chemically, the solution consists of potassium dichromate dissolved in water and sulfuric acid. While potassium dichromate acts as a strong oxidizing agent, the sulfuric acid enhances the oxidation effect and lowers the pH of the solution, which helps to improve oxidation.

When the solution is used, a series of chemical reactions occur. The potassium dichromate reacts with the organic matter and oxidizes it. The sulfuric acid assists this oxidation and provides an appropriate proton concentration. This results in a specific coloration of the organic substance.

The functioning of the potassium dichromate-sulfuric acid solution is based on its strong oxidative effect. Through the targeted oxidation of organic substances, it enables a differentiated presentation in analytical chemistry and histology.
