Lugol's solution can also be used in various experiments to observe how a cell membrane uses osmosis and diffusion. Lugol's solution is also used in the marine aquarium industry. Lugol's solution provides a strong source of free iodine and iodide to reef inhabitants and macroalgae.
Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine.Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.
Lugol's solution or Lugol's iodine (IKI) is a brown solution that turns black in the presence of starches and can be used as a cell stain, making the cell nuclei more visible. Used with common vinegar (acetic acid), Lugol's solution is used to identify pre-cancerous and cancerous changes in cervical and vaginal tissues during "Pap smear" follow ...
Purified water is 50 mL and the balance is alcohol. This 7% tincture solution is about 3.5 times more concentrated than USP 2% tincture. [citation needed] As in the case of Lugol's iodine, the role of iodide in the solution is to increase the solubility of the elemental iodine, by turning it to the soluble triiodide anion I 3 −. However ...
Aqueous KI 3 (Lugol's iodine) solution is used as a disinfectant and as an etchant for gold surfaces. Potassium iodide and silver nitrate are used to make silver(I) iodide, which is used for high speed photographic film and for cloud seeding: KI (aq) + 9 AgNO 3 (aq) → AgI (s) + KNO 3 (aq)
properly diluted chlorine preparations (f.e. Dakin's solution, 0.5% sodium or potassium hypochlorite solution, pH-adjusted to pH 7–8, or 0.5–1% solution of sodium benzenesulfochloramide (chloramine B)), some; iodine preparations, such as iodopovidone in various galenics (ointment, solutions, wound plasters), in the past also Lugol's solution,
Staining solutions are one way to make comparative analysis of starch granules more accessible, depending on what type of stain is specifically used. For example, as stated by Kovárník and Benes, Lugol's solution stains the grains a dark blue color, in order to distinguish the starch grain from other common structures that can appear similar ...
