(cupric nitrate), Cu(NO3)2; white (slightly green) crystals, which upon heating break down into CuO, NO2, and O2. Anhydrous Cu(NO3)2can be obtained from its concentrated nitric-acid solutions. The form most often isolated from aqueous solutions is Cu(NO3)2· 6H2O—dark blue crystals wi...
Besides, it is soluble in nitric acid, hot concentrated sulfuric acid while insoluble in cold and hot water. Its product categories are including Metals; Inorganics; Certified Reference Materials(CRMs); Labware; Metal; Tubing; Analytical/Chromatography; Elemental Analysis; Spectroscopy; Industrial Raw ...
Cooling grids and bends of the high silicon copper cast iron concentrated nitric acid condenser are manufactured by high silicon copper cast iron. The high silicon copper cast iron concentrated nitric acid condenser has the advantages of being improved in toughness and not easy to crack, and the ...
