• Microbiology – Commonly used in microbiology to stain bacterial spores and other structures, this aids in visualization of the spores and other structures under a microscope.
• Disinfectant: It has strong antiseptic properties due to the presence of iodine and can be used to disinfect wounds, ulcers, and burns.
• Staining agent: It is used as a staining agent in histology to visualize cell structures such as nuclei and chromosomes, it is also used in the textile industry as a coloring agent.
• Gold mining: Lugol’s solution is used in gold mining to detect the presence of gold in ores. The solution is added to the ore and the iodine reacts with the gold, resulting in the formation of a brown color.
• In the medical field, Lugol’s Solution is used as a disinfectant for wounds, ulcers and burns, it is also used in the treatment of iodine deficiency disorders such as goiter and cretinism.
