Zinc iodide is often used as an x-ray opaque penetrant in industrial radiography to improve the contrast between the damage and intact composite. [8] [9]United States patent 4,109,065 [10] describes a rechargeable aqueous zinc-halogen cell that includes an aqueous electrolytic solution containing a zinc salt selected from the class consisting of zinc bromide, zinc iodide, and mixtures thereof ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Iodine rarely occurs naturally in mineral form, so it comprises a very small portion of rocks by mass. [2] Sedimentary rocks have higher concentrations of iodine compared to metamorphic and igneous rocks. [4] Due to the low concentration of iodine in rocks, weathering is a minor flux of iodine to soils and the freshwater hydrosphere. [1]
Carrying iodine for water purification is an imperfect but lightweight solution for those in need of field purification of drinking water. Kits are available in camping stores that include an iodine pill and a second pill (vitamin C or ascorbic acid) that will remove the iodine taste from the water after it has been disinfected. The addition of ...
Zinc is an inexpensive and effective part of treatment of diarrhea among children in the developing world. Zinc becomes depleted in the body during diarrhea and replenishing zinc with a 10- to 14-day course of treatment can reduce the duration and severity of diarrheal episodes and may also prevent future episodes for as long as three months.

Pictured recipe: Tahini-Yogurt Dip. Yogurt, milk, cheese and other dairy foods are all good sources of iodine—3/4 cup of plain, fat-free Greek yogurt provides about 60% of your daily iodine needs.
Brine mining is the extraction of useful materials (chemical elements or compounds) which are naturally dissolved in brine.The brine may be seawater, other surface water, groundwater, or hyper-saline solutions from several industries (e.g., textile industries). [1]
