Potassium dichromateis used mostly for the analysis of iron (seeTable 12-4). Either SnCl2or the zinc reductor is used for the adjustment of the iron to the 2+oxidationstate.Sodiumdiphenylaminesulfonate(H3PO4must be present) or 5,6-dimethylferroin andN-phenylanthranilic acid can be used as ...
(hydroxide in, e.g., strong bases, oil sweetening, CO2absorbent,chromate and dichromatesas oxidants, and carbonate in the glass industry), fertilizers (nitrate, carbonate, chloride, bromide, and sulfate), detergents and soaps (hydroxide and carbonate), and coolants in nuclear reactors (NaK ...
potassium: Symbol K. A soft silverymetallic element belonging to group1 (formerly IA) of the periodic table(see alkali metals); a.n. 19; r.a.m.39.098; r.d. 0.86; m.p. 63.7°C; b.p.774°C. The element occurs in seawaterand in a number of minerals,such as sylvite (KCl), carn...
Potassium dichromate (K2Cr2O7) is an inorganic chemical reagent that is normally used as an oxidizer in industrial and laboratory applications. It is used to oxidize alcohols and convert primary alcohols to aldehydes and sometimes carboxylic acids. Unlik
Potassium ferricyanide(III) is a potassium salt widely employed as an external indicator in potassium dichromate titrations. A sensor containing potassium ferricyanide assisted enzyme electrode for estimating maltose and glucose in samples has been reported. Addition of potassium ferricyanide in the catholy...
Melatonin (ML) is a potent antioxidant that reduces oxidative stress. This study was designed to examine the protective effect of melatonin on potassium dichromate- (PDC-) induced male reproductive t...

A molecular mechanism for the oxidation of paminophenol using potassium dichromate is proposed. This mechanism explains the specific features of p-aminophenol oligomerization and polymerization reactions. Spectroscopic studies using IR, UV鈥搗is and elemental analysis have evidenced the structure of ...
Potassium is non-water soluble, but it does react with water as was explained earlier. Potassium compounds may be water soluble. Examples are potassium dichromate with a water solubility of 115 g/L, potassium permanganate with a water solubility of 76 g/L, potassium iodide with a water solubil...
These methods were based on the oxidation of the drug by different inorganic oxidants: ceric ammonium sulfate, potassium permanganate, ammonium molybdate, ammonium metavanidate, chromium trioxide, potassium dichromate, potassium iodate, and potassium periodate. The oxidation reactions were performed in ...
