Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na + ) and iodide anions (I − ) in a crystal lattice .
Diiodomethane or methylene iodide, commonly abbreviated "MI", is an organoiodine compound. Diiodomethane is a very dense colorless liquid; however, it decomposes upon exposure to light liberating iodine, which colours samples brownish. It is slightly soluble in water, but soluble in organic solvents.

A combination of methyltrichlorosilane and sodium iodide can be used to cleave carbon-oxygen bonds such as methyl ethers. R'OR + MeSiCl 3 + NaI + H 2 O → R'OH + RI + MeSiCl 2 (OH) + NaCl. Esters and lactones can also be cleaved with methyltrichlorosilane and sodium iodide to give the corresponding carboxylic acids. Acetals convert to carbonyl ...
The reaction product of ethylene oxide with acyl chlorides in the presence of sodium iodide is a complex iodoethyl ester: [56] (CH 2 CH 2)O + RCOCl + NaI → RC(O)–OCH 2 CH 2 –I + NaCl. Heating ethylene oxide to 100 °C with carbon dioxide, in a non-polar solvent in the presence of bis-(triphenylphosphine)-nickel(0) results in ethylene ...
Rubidium iodide forms colorless crystals, and has a red-violet flame color. The refractive index of the crystals is n D = 1.6474. [2] It reacts with halogens to form polyhalides: RbI 3, RbICl 2, RbICl 4. [3] It is easily soluble in water, liquid ammonia, sulfuric acid, RbI·6NH 3 and RbI·3SO 2. Rubidium iodide is soluble only in the following ...
Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite. [3] Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite: AgNO 3 (aq) + NaNO 2 (s) → NaNO 3 (aq) + AgNO 2 ...
