Reaction of copper with nitric acid

Declan Fleming shows how copper can in fact react with some acids by demonstrating the reaction of copper and nitric acid, producing a visually stunning reaction. Read the article that accompanies this video in the November 2011 issue of Education in Chemistry at rsc.li/EiC611ec
This is part of the Education in Chemistry Exhibition Chemistry series: chemistry demonstrations to capture your students' imaginations: rsc.li/EiCExChem

    Yes, you can dilute it with deionized water, and if you add NaOH (sodium hydroxide) a drop at a time, a blue precipitate will form, Cu(OH)2. Copper hydroxide. You can test the liquid after several drops at a time with litmus paper to know when it's turned basic. Add more water and heat, stirring until it boils, and the Cu(OH)2 will turn into CuO, copper(ii) oxide. Filter this, and use H2SO4 (sulfuric acid) to drain it into a beaker, then add zinc, which will dissolve and leave you with pure Cu.

  • @Squish120

    Wow that's a lot of NO2, you can prevent the formation of NO2 by using hydrogen peroxide in with the nitric acid, to oxidise the NO2 back to HNO3 as its formed. This way you get more efficiency from the acid, able to react with a larger amount of material.

  • @declan.fleming

    @declan.fleming

    9 жыл бұрын

    Collectively we just call these delivery tubes. The water is drawn back in in a process of "suck back" - the air in the main flask gets quite hot during the reaction and expands. As the reaction subsides, heat is lost to the surroundings and the gas begins to contract, drawing the water back up the tube as the pressure drops. This would only happen a little but for the water then dissolving the NO2 gas in the flask .. as gas particles dissolve in the water, the pressure drops still further and draws even more water in, dissolving more gas .. etc etc.

    The green material produced at first in the reaction is not copper nitrate. Copper nitrate or rather the [Cu(H2O)6]2+ ion is blue. The green color is due to a copper II nitrato complex. Exact structure of these complexes are not known,but equation below is a likely possibility. Equations Cu + 4 H3O+ + 4 NO3− → [Cu(H2O)4(NO3)2] + 2 H2O + 2 NO2 [Cu(H2O)4(NO3)2] + 2 H2O → [Cu(H2O) 6]2+ + 2 NO3−
