Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water ...
My mistake.. well I think that the copper recovery cannot become high, I'm just having problems determining whether it has no effect or reduces copper recovery. Does it have to do with limiting reactants or is there some logic I'm missing? Logged Borek...
Reaction equation: Cu 4HNO3 → Cu(NO3)2 2NO2 ↑ 2H2O2Cu(NO3)2 2Na2CO3 H2O → CuCO3 Cu(OH)2 4NaNO3 CO2 ↑ 2Cu(NO3)2 4NaHCO3 → CuCO3 Cu(OH)2 4NaNO3 3CO2 ↑ H2O operation method: after electrolytic copper reacts with concentrated nitric acid to generate copper, it reacts ...
Because copper lies belowhydrogenin theelectromotive series, it is not soluble inacidswith the evolution of hydrogen, though it will react with oxidizing acids, such asnitricand hot, concentratedsulfuric acid. Copper resists the action of theatmosphereandseawater. Exposure for long periods toair, ho...
In one disclosed embodiment, the material which promotes the formation of nitrous acid increases in concentration toward the substrate, or board to which the copper is bonded. The nitrous acid reacts vigorously with the copper, and the etch rate increases as the etch progresses through the copper...
Copper(II) nitrate reacts with ether forming a complex. 6.5 Hazard Copper(II) nitrate is moderately toxic by ingestion. Skin or eye contact can cause irritation. LD50 oral (rat): 940 mg/kg. Copper(II) nitrate, being an oxidizing agent, can undergo violent reactions with readily oxidizable...
Copper reacts with nitrogen oxides at temperatures of incandescence, in particular, with NO and N2O to give Cu2O and with NO2 to give CuO. The carbides of copper, Cu2C2 and CuC2, can be obtained by the action of acetylene on the ammonia solutions of copper salts. The normal electrode ...
Copper (II) nitrate can react with acetic anhydride to induce the nitration of aromatic compounds such as benzene.Uses: Copper (II) nitrate can be used in the production of pyrotechnics and blue colors and coats. It is also used as a classical demonstration of the voltaic cell due to the ...
