The Iodine Solution 5% (Lugol) by Dinâmica, available at LojaLab, is an aqueous solution containing iodine and potassium iodide in ultrapure water. Iodide increases iodine solubility through formation of polyiodide species, allowing the solution to serve as a reagent in starch tests, staining and laboratory procedures requiring available iodine in an aqueous medium.
Characteristics
- Aqueous iodine solution solubilized with potassium iodide
- Nominal iodine concentration of 5%
- Characteristic dark-brown color of iodine species in solution
- Reacts with starch to produce a blue to dark-blue complex under suitable conditions
- Laboratory reagent mixture with no pharmaceutical or food purpose.
Applications
- Qualitative starch testing in foods, plant materials and compatible samples
- Staining and contrast enhancement in specified microscopy preparations
- Educational assays involving polysaccharides, equilibrium and iodine chemistry
- Preparation of derived reagents when a 5% aqueous iodine solution is specified.
