Its use as a food dye was legalized in the US by the Pure Food and Drug Act of 1906. [6] By early 1920s, it was produced mainly for the food industry, [ 7 ] with 2,170 pounds (0.98 t) made in America in 1924, [ 8 ] rising to 9,468 pounds (4.29 t) in 1938 [ 9 ] and approximately 50 tons in 1967.
The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides. A test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. [2] Aqueous solutions of iodide salts dissolve iodine better than pure ...
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...

The center petitioned the FDA in 2008 to ban eight approved food dyes, force manufacturers to put a warning label on products containing the chemicals, and require new testing.
(Nonetheless, nitrogen triiodide is named as an iodide as it is analogous to the other nitrogen trihalides.) [7] Given the large size of the iodide anion and iodine's weak oxidising power, high oxidation states are difficult to achieve in binary iodides, the maximum known being in the pentaiodides of niobium, tantalum, and protactinium. Iodides ...
