The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...
A solution of a carbonyl compound is added to a Grignard reagent. (See gallery) An example of a Grignard reaction (R 2 or R 3 could be hydrogen). The Grignard reaction (French:) is an organometallic chemical reaction in which, according to the classical definition, carbon alkyl, allyl, vinyl, or aryl magnesium halides (Grignard reagent) are added to the carbonyl groups of either an aldehyde or ...
As is common for reactions involving solids and solution, the formation of Grignard reagents is often subject to an induction period. During this stage, the passivating oxide on the magnesium is removed. After this induction period, the reactions can be highly exothermic.
nickel(II) chloride hexahydrate NiCl 2 ·6H 2 O is made green by the hydrated nickel(II) chloride [NiCl 2 (H 2 O) 4]. sodium chloride NaCl and magnesium sulfate heptahydrate MgSO 4 ·7H 2 O are colorless or white because the constituent cations and anions do not absorb light in the part of the spectrum that is visible to humans.

Magnesium chloride (E511 [19]) is an important coagulant used in the preparation of tofu from soy milk. In Japan it is sold as nigari ( にがり , derived from the Japanese word for "bitter"), a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated.
