Ammonium iodide is the inorganic compound with the formula NH 4 I. A white solid. It is an ionic compound, although impure samples appear yellow. This salt consists of ammonium cation and an iodide anion. [1] It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes.
Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt. 2 KIO 3 + (NH 4) 2 SO 4 → 2 NH 4 IO 3 + K 2 SO 4. Unlike other iodates, ammonium iodate can't be prepared by dissolving iodine in an ammonium hydroxide solution, instead the highly explosive nitrogen triiodide is formed. 3 I 2 + 5 NH ...
It is the iodide salt of the dimethylaminomethylene cation [(CH 3) 2 NCH 2] +. The dimethylaminomethylene cation is a strong dimethylaminomethylating agent, used to prepare derivatives of the type RCH 2 N(CH 3) 2. [1] [2] Enolates, silyl enol ethers, and even more acidic ketones undergo efficient dimethylaminomethylation.
Similarly to potassium iodide (KI), sufficient consumption of tetraglycine hydroperiodide tablets may protect the thyroid against uptake of radioactive iodine. A 1995 study found that daily consumption of water treated with 4 tablets containing tetraglycine hydroperiodide reduced the uptake of radioactive iodine in human subjects to a mean of 1 ...
For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The typical adult dose is one 130 mg tablet per 24 hours, supplying 100 mg (100,000 micrograms ) of ionic iodine (the typical daily dose of iodine for normal health is on the ...
Aug. 11—WILKES-BARRE — The Pennsylvania Department of Health (DOH) will offer free potassium iodide, or KI, tablets on Aug. 22 to Pennsylvanians who live or work within 10 miles of the state's ...
