silver iodide precipitate formula

5. The silver contamination arises because AgI is highly photosensitive. iodide ions give a yellow precipitate of silver iodide; For example: silver nitrate + sodium bromide → sodium nitrate + silver bromide. AgNO 3 (aq) + NaBr(aq) → NaNO 3 (aq) + AgBr(s) Note: This is an unusual reaction as the precipitate dissolves in excess iodide solution and disappears as a complex ion is formed. As part of the U.S. Department of the Interior, Bureau of Mines, mission to assure a viable domestic minerals and materials economy, research is being conducted to investigate methods for recovering accessory elements from solutions resulting from hydrometallurgical processing of base-metal sulfide concentrates. Silver chloride is a chemical compound with the chemical formula Ag Cl.This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl + and Pb 2+).Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grey to black or purplish coloration to some samples. Silver iodide should be stored in cool, dark areas, away from the above materials. Silver iodide may form explosive compounds with sodium, potassium, acetylene, ammonia, and hydrogen peroxide. KI(aq) + AgNO 3 (aq) KNO 3 (aq) + AgI(s) A yellow white precipitate of silver iodide, AgI is produced. 6. Silver iodide is an inorganic compound with the formula AgI. Potassium iodide + silver nitrate potassium nitrate + silver iodide. Before shipping silver iodide, consult with the regulatory requirements of the US Department of Transportation. This property is exploited in silver-based photography. Silver iodide is also used as an antiseptic and in cloud seeding. The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a gray coloration.
