    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.

  3. Magnesium chloride - Wikipedia

    en.wikipedia.org/wiki/Magnesium_chloride

    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.

  4. Sodium chloride - Wikipedia

    en.wikipedia.org/wiki/Sodium_chloride

    Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic, and occurs as the mineral halite. In its edible form, it is commonly used as a condiment ...

  5. Silver chloride - Wikipedia

    AgNO 3 + NaCl → AgCl↓ + NaNO 3 2 AgNO 3 + CoCl 2 → 2 AgCl↓ + Co(NO 3) 2. It can also be produced by the reaction of silver metal and aqua regia; however, the insolubility of silver chloride decelerates the reaction. Silver chloride is also a by-product of the Miller process, where silver metal is reacted with chlorine gas at elevated ...

    Chloride-type nigari salts or lushui (Traditional: 鹵水, 滷水; Simplified: 卤水; Pinyin: lǔshuǐ) – Magnesium chloride and calcium chloride: Both of these salts are highly soluble in water and affect soy protein in the same way, whereas gypsum is only very slightly soluble in water and acts differently in soy protein precipitation, the ...

  7. Grignard reaction - Wikipedia

    en.wikipedia.org/wiki/Grignard_reaction

    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 ...

  8. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    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 ...

  9. Acid–base reaction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_reaction

    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.
