Iodine solution is widely used as a disinfectant and antiseptic in medical settings to clean wounds, surgical sites, and skin before procedures. It effectively kills bacteria, viruses, and fungi, making it essential for preventing infections. In laboratories, it serves as a staining agent to detect starch in biological samples, turning blue-black in the presence of starch, and as a titrant in iodometric titrations for quantitative analysis of reducing agents and oxidants. It is also employed in water treatment to purify drinking water by eliminating harmful microorganisms. Additionally, iodine solution is used in the dairy and food industry to sanitize equipment and surfaces, ensuring hygiene and safety in food production.
