Iodine solution, also known as tincture of iodine or iodine spirit, is a chemical preparation used in a variety of applications. This useful product is widely used both in households and in industry. In this blog post, we will take a closer look at the properties, mode of action, and various uses of iodine solution.

What is iodine solution?

Iodine solution is a solution of elemental iodine in ethanol or isopropanol. Iodine is a chemical element that exists at room temperature as a solid, crystalline substance. By dissolving it in a suitable solvent such as alcohol, the iodine solution is formed, which has a brown-violet coloration.

The concentration of iodine in the solution can vary, usually ranging between 2% and 7%. The higher the iodine content, the more intense the coloration of the liquid.

Chemical composition and properties

Iodine solution consists of the following main components:

• Elemental iodine (I₂)
• Ethanol or isopropanol as solvents

In addition to these main components, depending on the application and manufacturer, further additives such as emulsifiers, stabilizers, or dyes may be included.

The iodine solution is characterized by the following properties:

• Brown-violet coloration
• Characteristic, pungent odor
• Antiseptic and disinfectant effect
• Oxidative properties
• Volatile due to the alcohol content
