POTASSIUM DICHROMATE (7778-50-9)
Potassium Bichromate · K2Cr2O7
Potassium dichromate, K2Cr2O7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health. It is a crystalline ionic solid with a very bright, red-orange color.
Sodium dichromate (10588-01-9, 7789-12-0, 10588-01-9, 34493-01-1)
sodium bichromate · Na2Cr2O7 · sodium bichromate, dihydrate
Sodium dichromate is the inorganic compound with the formula Na2Cr2O7. Usually, however, the salt is handled as its dihydrate Na2Cr2O7·2H2O. Virtually all chromium ore is processed via conversion to sodium dichromate and virtually all compounds and materials based on chromium are prepared from this salt.
SODIUM CHROMATE (12680-48-7, 7775-11-3)
sodium chromate(VI) · sodium chromate(VI), 51Cr-labeled cpd · chromium sodium oxide (CrNa2O4)
Sodium chromate is the inorganic compound with the formula Na2CrO4. It exists as a yellow hygroscopic solid, which can form tetra-, hexa-, and decahydrates. It is an intermediate in the extraction of chromium from its ores.
POTASSIUM CHROMATE (7789-00-6, 18453-57-1)
potassium chromate(VI) · dipotassium chromate · bipotassium chromate
Potassium chromate is the inorganic compound with the formula (K2CrO4). This yellow solid is the potassium salt of the chromate anion. It is a common laboratory chemical, whereas sodium chromate is important industrially.
CALCIUM CHROMATE (13765-19-0, 12205-18-4, 53568-70-0)
calcium chromate(VI), dihydrate · calcium chromate(VI)
Calcium chromate (CaCrO4) is a bright yellow solid. It normally occurs as the dihydrate, although the very rarely natural (mineral) form, known as hashemite, is anhydrous.
STRONTIUM CHROMATE (7789-06-2)
Strontium chromate is a chemical compound, with the formula SrCrO4.
CHROMIC ACID (1333-82-0, 7738-94-5)
The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate, which may contain a variety of compounds, including solid chromium trioxide. This kind of chromic acid may be used as a cleaning mixture for glass. Chromic acid may also refer to the molecular species, H2CrO4 of which the trioxide is the anhydride.
AMMONIUM DICHROMATE (7789-09-5)
Ammonium dichromate is the inorganic compound with the formula (NH4)2Cr2O7. In this compound, as in all chromates and dichromates, chromium is in a +6 oxidation state, commonly known as hexavalent chromium. It is a salt consisting of ammonium ions and dichromate ions.
BARIUM CHROMATE (10294-40-3)
Barium chromate, named barium tetraoxochromate(VI) by the IUPAC, is a yellow sand like powder with the formula BaCrO4. It is a known oxidizing agent and produces a green flame when heated, a result of the barium ions.
AMMONIUM CHROMATE (52110-72-2, 7788-98-9)
Ammonium chromate is a salt with the formula (NH4)2CrO4. It forms yellow, monoclinic crystals; made from ammonium hydroxide and ammonium dichromate; used in photography as a sensitizer for gelatin coatings. It's often used in photography, textile printing, and fixing chromate dyes on wool.
SILVER CHROMATE (7784-01-2)
Silver chromate (Ag2CrO4) is a brown-red monoclinic crystal and is a chemical precursor to modern photography. It can be formed by combining silver nitrate (AgNO3) and potassium chromate (K2CrO4) or sodium chromate (Na2CrO4). This reaction has been important in neuroscience, as it is used in the "Golgi method" of staining neurons for microscopy: the silver chromate produced precipitates inside neurons and makes their morphology visible.
Pyridinium dichromate (20039-37-6)
The Cornforth reagent or pyridinium dichromate (PDC) is a pyridinium salt of dichromate with the chemical formula [C5H5NH]2[Cr2O7]. This compound is named after the Australian-British chemist Sir John Warcup Cornforth (b. 1917) who introduced it in 1962.
Cesium chromate (13454-78-9)
Caesium chromate, the caesium salt of chromic acid, is used to produce caesium vapour by reaction with silicon, boron, or titanium, which is used to in the final stages of creating vacuum tubes; the caesium vapour reacts with the remaining gases, including nitrogen and oxygen.
Nickel chromate (14721-18-7)
Nickel (II) Chromate (NiCrO4) is an acid-soluble compound, red-brown in color, with high tolerances for heat. It and the ions that compose it have been linked to tumor formation and gene mutation, particularly to wildlife.
