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 ...
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.
In complex reactions, stoichiometries are often represented in a more compact form called the stoichiometry matrix. The stoichiometry matrix is denoted by the symbol N. [10] [11] [12] If a reaction network has n reactions and m participating molecular species, then the stoichiometry matrix will have correspondingly m rows and n columns.
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
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.
