Potassium dichromate, K 2 Cr 2 O 7, 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.
The chromate and dichromate ions are fairly strong oxidizing agents. Commonly three electrons are added to a chromium atom, reducing it to oxidation state +3. In acid solution the aquated Cr 3+ ion is produced. Cr 2 O 2− 7 + 14 H + + 6 e − → 2 Cr 3+ + 7 H 2 O ε 0 = 1.33 V
It's a good reducing agent and is used in the Wolff-Kishner reaction for reducing carbonyls to its corresponding alkanes. used as a foaming agent in preparing polymer foams; also a precursor to polymerization catalysts and pharmaceuticals; also as an Oxygen scavenger in Power Plants: Hydrazoic acid
Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals. 2 Li (s) + H 2(g) → 2 LiH (s) [ a ] Hydrogen (whose reduction potential is 0.0) acts as an oxidizing agent because it accepts an electron donation from the reducing agent lithium (whose reduction potential is -3.04), which causes ...
