I need to know, if copper nitrate (produced by the reaction of nitric acid and copper) a solution or a precipitate??my notes say it is a blue-green precipitate.my teacher says it is a blue ppt.my textbook says it is a blue green solution??any help?!
the answer is - it depends nitrates are generally quite soluble but of course it has a limit so if you turn enough copper into its nitrate, then, yes, you will get some precipitate in addition to that which is dissolved.
it is a denitrification. the traditional reaction is Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag. besides the undeniable fact that, the copper might have catalysed right here reaction. 2AgNO3 -> 2Ag + 2NO2 + O2 besides the undeniable fact that, i'm undecided in any respect, besides the undeniable fact that it is the only one i will think of of.
Copper nitrate is usually a solid, but it is very hygroscopic - a bottle of dry crystals will rapidly accumulate water and from a blue-grn solution if precautions are not taken to keep the water out. - that might account for the different answers you have.
Most of the nitrate salts are soluble in aqueous solution .Hence Copper sulphate in aqueous solution is a blue green solution.In aqueous solution Cu2+ ion is hydrated and colour is due the d-d transition.
Copper(II) nitrate is the chemical compound with the formula Cu(NO3)2. Commonly referred to simply as copper nitrate, the anhydrous form is a blue, crystalline solid. Hydrated forms of copper nitrate, also blue, are commonly used in school laboratories to demonstrate chemical voltaic cell reactions. The Roman numeral sign is to specify that the copper has an oxidation state of +2. Synthesis and reactions Cu(NO3)2 forms when copper metal is treated with N2O4 Cu + 2 N2O4 → Cu(NO3)2 + 2 NO Hydrated copper nitrate can be prepared by hydrolysis of the anhydrous material or by treating copper metal with an aqueous solution of silver nitrate or dilute nitric acid: Cu + 4 HNO3 → Cu(NO3)2 + 2 H2O + 2 NO2 Copper nitrate can be used to generate nitric acid by heating it until decomposition and passing the fumes directly into water. This method is similar to the last step in the Ostwald process. The equations are as follows: 2 Cu(NO3)2 → 2 CuO + 4 NO2 + O2 3NO2 + H2O → 2HNO3 + NO Hope i helped. Good luck.
