  2. Zinc chromate - Wikipedia

    en.wikipedia.org/wiki/Zinc_chromate

    Zinc chromate, Zn Cr O 4, is a chemical compound, a salt containing the chromate anion, appearing as odorless yellow powder or yellow-green crystals, but, when used for coatings, pigments are often added. [2] [3] [4] It is used industrially in chromate conversion coatings, having been developed by the Ford Motor Company in the 1920s. [5]

  3. Zinc perchlorate - Wikipedia

    en.wikipedia.org/wiki/Zinc_perchlorate

    The compound decomposes when heated to high temperatures and may explode if heated too strongly. Like most other perchlorates such as copper perchlorate and lead perchlorate , zinc perchlorate is prone to deliquescence .

  4. Zinc compounds - Wikipedia

    en.wikipedia.org/wiki/Zinc_compounds

    Compounds with zinc in the oxidation state +1 are extremely rare. [5] The compounds have the formula RZn 2 R and they contain a ZnZn bond analogous to the metal-metal bond in mercury(I) ion, Hg 2 2+. In this respect zinc is similar to magnesium where low-valent compounds containing a Mg — Mg bond have been characterised. [6]

  5. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  6. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.

    naming of cluster compounds; allowed names for inorganic acids and derivatives; naming of solid phases e.g. non-stoichiometric phases; For a simple compound such as AlCl 3 the different naming conventions yield the following: compositional: aluminium trichloride (stoichiometrically) or dialuminium hexachloride ; substitutional: trichloralumane

  9. Color of chemicals - Wikipedia

    en.wikipedia.org/wiki/Color_of_chemicals

    Similarly, color is due to the energy absorbed by the compound, when an electron transitions from the HOMO to the LUMO. Lycopene is a classic example of a compound with extensive conjugation (11 conjugated double bonds), giving rise to an intense red color (lycopene is responsible for the color of tomatoes).
