  2. Chromium compounds - Wikipedia

    en.wikipedia.org/wiki/Chromium_compounds

    Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals . The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist.

  4. Chromate and dichromate - Wikipedia

    en.wikipedia.org/wiki/Chromate_and_dichromate

    Chromate containing minerals are rare. Crocoite, PbCrO 4, which can occur as spectacular long red crystals, is the most commonly found chromate mineral. Rare potassium chromate minerals and related compounds are found in the Atacama Desert. Among them is lópezite – the only known dichromate mineral. [10]

    For compounds containing an oxyanion of chromium in oxidation state of +3; For other compounds of chromium(III) as a means of distinguishing a chemical species such as hexacyanochromite(III). [Cr(CN) 6] 3− from an analogous compound in which chromium is a different oxidation state. The mineral chromite is an iron chromium oxide with empirical ...

  6. Tin - Wikipedia

    en.wikipedia.org/wiki/Tin

    Tin(II) fluoride is added to some dental care products [111] as stannous fluoride (SnF 2). Tin(II) fluoride can be mixed with calcium abrasives while the more common sodium fluoride gradually becomes biologically inactive in the presence of calcium compounds. [112] It has also been shown to be more effective than sodium fluoride in controlling ...

  7. Titanium compounds - Wikipedia

    en.wikipedia.org/wiki/Titanium_compounds

    The +4 oxidation state dominates titanium chemistry, [1] but compounds in the +3 oxidation state are also numerous. [2] Commonly, titanium adopts an octahedral coordination geometry in its complexes, [3] [4] but tetrahedral TiCl 4 is a notable exception. Because of its high oxidation state, titanium(IV) compounds exhibit a high degree of ...

  8. Chromium(II) chloride - Wikipedia

    en.wikipedia.org/wiki/Chromium(II)_chloride

    Chromium(II) chloride describes inorganic compounds with the formula Cr Cl 2 (H 2 O) n. The anhydrous solid is white when pure, however commercial samples are often grey or green; it is hygroscopic and readily dissolves in water to give bright blue air-sensitive solutions of the tetrahydrate Cr(H 2 O) 4 Cl 2 .

  9. Organotin chemistry - Wikipedia

    en.wikipedia.org/wiki/Organotin_chemistry

    Organotin compounds are those with tin linked to hydrocarbons. The compound on the picture is trimethyltin chloride, an example of organotin compounds.. Organotin chemistry is the scientific study of the synthesis and properties of organotin compounds or stannanes, which are organometallic compounds containing tin–carbon bonds.
