MARTIN-SANCHEZ, Manuela; MARTIN-SANCHEZ, María Teresa  and  PINTO, Gabriel. Lugol reactive: History of Discovery and teaching applications. Educ. quím [online]. 2013, vol.24, n.1, pp.31-36. ISSN 0187-893X.

Our paper is a brief historical study of aqueous solutions of potassium iodide and iodine. It also analyzes why, in Biology and Medicine, these solutions are known as Lugol reactive. Moreover, we study their use for educational purposes to deepen in various topics such as redox reactions and the relationship between solubility and bond types.

Keywords : Lugol Reactive; redox reactions; chemical bond; chemistry teaching.
