Oxidizing agents identification

Potassium percarbonate is used in photography under the name Antihypo for removing the last traces of thiosulfate from film and paper. It is a strong oxidizing agent in certain chemical analysis and in microscopic identification of tubercle bacilli. 

Perhaps the criteria which lead most directly to a conclusion are those which were applied in the first unambiguous demonstration of this kind of mechanism for reactions between metal ion complexes. When Co(NH3)5CP" reacts with Cr " (aq) in acidic solution, the products are Co " (aq), NH4+ and Cr(H20)5CF", the latter being formed virtually quantitatively. In the absence of further information, the identification of products would by no means provide proof of mechanism. The additional information which is pertinent to the issue follows (a) the oxidizing agent, Co(NH3)5CP", undergoes aquation much less rapidly than it does reduction by Cr (aq) ... 

Aluminum nitrate, A1(N03)3, is a white, crystalline material that is soluble in cold water. It is a powerful oxidizing agent that decomposes at approximately SOOT. Aluminum nitrate should not be stored near combustible materials. The four-digit UN identification number is 1438. The primary uses are in textiles, leather tanning, as an anticorrosion agent, and as an antiperspirant. 

Potassium nitrate (saltpeter) has a molecular formula of KNOj. It is found as a transparent to white crystalline powder and as crystals. Potassium nitrate is water-soluble and is a dangerous fire and explosion risk when heated or shocked or in contact with organic materials. It is a strong oxidizing agent, with a four-digit UN identification number of 1486. Potassium nitrate is used in the manufacture of pyrotechnics, explosives, and matches. It is often used in the illegal manufacture of homemade pyrotechnics and explosives. 

As also the oxides of phosphor, they form polymers willingly. Sulfuric acid is a strong acid, a dehydrating agent and an oxidizing agent. Most inorganic salts of the anion sulfate are water soluble. One exception is barium sulfate and the characteristic of this salt is used in the test. The identification test for sulfates is special since the purposes of the different steps of the analysis are explained in parentheses in the pharmacopoeial text. 

Arene oxidation leading to direct C—C bond formation allows rapid assembly of complex and ste-reochemically rich carbocyclic ring systems. Crucial to the success of this approach is the identification of carbon nucleophiles that are stable in the presence of oxidation agents typically used to effect arene dearomatization. Enolates and enol ethers are problematic as these species undergo rapid oxidation under mild conditions [62]. Stabilized enolates (such as those derived from activated methylenes) exhibit greater compatibility with oxidation conditions and have been used as nucleophilic participants in intramolecular oxidative dearomatizations initiated by [Fe(CN)g] and PIDA to afford spirocyclic cyclohexadienones [63, 64]. Detailed mechanisms for these reactions have not been defined so it is unclear whether bond formation occurs through ionic or radical intermediates.
