Copper(I) iodide reacts with mercury vapors to form brown copper(I) tetraiodomercurate(II): 4 CuI + Hg → (Cu +) 2 [HgI 4] 2− + 2 Cu. This reaction can be used for the detection of mercury since the white CuI to brown Cu 2 [HgI 4] color change is dramatic. Copper(I) iodide is used in the synthesis of Cu(I) clusters such as [Cu 6 I 7] −. [10]

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color . Copper also has a range of different organic and inorganic salts , having varying oxidation states ranging from (0,I) to (III).
Some copper proteins form oxo complexes, which also feature copper(III). [20] With tetrapeptides, purple-colored copper(III) complexes are stabilized by the deprotonated amide ligands. [21] Complexes of copper(III) are also found as intermediates in reactions of organocopper compounds. [22] For example, in the Kharasch–Sosnovsky reaction.
Marshite occurs naturally in geologic supergene deposits at Chuquicamata, Chile which are heavily mined for copper. [11] Additional research on the rocks and minerals from this area show that iodine isotopes found in minerals, such as marshite, and soils can be used to understand the processes that formed the supergene deposit.
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 ...
