Chromate and dichromate - Wikipedia
WebThe dichromate ion is a somewhat weaker base than the chromate ion: HCr 2 O − 7 ⇌ Cr 2 O 2− 7 + H +, pK = 1.18. The pK value for this reaction shows that it can be ignored at pH > 4. Oxidation–reduction properties. The chromate and dichromate ions are fairly strong oxidizing agents.
Potassium dichromate - Wikipedia
WebPotassium dichromate is one of the most common causes of chromium dermatitis; chromium is highly likely to induce sensitization leading to dermatitis, especially of the hand and forearms, which is chronic and difficult to treat. Toxicological studies have further illustrated its highly toxic nature.
Sodium dichromate - Wikipedia
WebDichromate and chromate salts are oxidizing agents. For the tanning of leather, sodium dichromate is first reduced with sulfur dioxide. In the area of organic synthesis, this compound oxidizes benzylic and allylic C-H bonds to carbonyl derivatives. For example, 2,4,6-trinitrotoluene is oxidized to the corresponding carboxylic acid.
