Project at a Glance Contents on the CD ROM
  • Potassium dichromate, K2Cr2O7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications.
  • It is a crystalline ionic solid with a very bright, red-orange color. It is also known as potassium bichromate; potassium salt and lopezite.
  • It is not combustible, but it is a strong oxidizer that enhances the combustion of other substances.
  • Reacts violently with hydrazine, anhydrous hydroxylamine, and mixtures of sulfuric acid and acetone but it not compatible with oxidizing agents and strong acids like hydrochloric, nitric.
  • Potassium dichromate may be used to prepare "chromic acid", which can be used for cleaning glassware and etching materials.
  • Potassium dichromate has important uses in photography and in photographic screen printing, where it is used as an oxidizing agent together with a strong mineral acid.
  • A potassium dichromate solution in sulfuric acid can be used to produce a reversal negative (i.e., a positive transparency from a negative film). This is effected by developing a black and white film but allowing the development to proceed more or less to the end point
  • Potassium dichromate paper can be used to test for sulfur dioxide, as it turns distinctively from orange to green. This is typical of all redox reactions where hexavalent chromium is reduced to the less harmful trivalent chromium.
  • K2Cr2O7 was a most effective strong inhibitor for corrosion protection of mild steel reinforcement in concrete.
  • Used in initiated polymerization of aniline in acidified aqueous medium was carried out as a function of parameters such as pH, aniline mole ratio, temperature and time.
  • The dissolution of chalcopyrite in acidic potassium dichromate solution is that the dissolution rate increased with increasing K2Cr2O7 concentration.
