Copper React with Nitric Acid

Copper reacts with nitric acid to produce copper nitrate, nitrogen dioxide, and water. This is an oxidation-reduction reaction, or redox reaction.  Chemical equation  Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) Products of the reaction  Copper nitrate: A blue crystalline solid Nitrogen dioxide: A reddish-colored, poisonous gas Water: A liquid Reaction conditions The reaction is dramatic and can be used to explain observations using the electrochemical series.  The reaction can be performed using copper turnings and concentrated nitric acid.  The reaction is violent and produces a thick red cloud of nitrogen dioxide gas.  The nitrogen dioxide gas is highly dangerous and can cause your lungs to fill up with fluid if you breathe it in.  Safety precautions  Perform the reaction in a fume cupboard or use a delivery tube to feed the gas into a glass of water to minimize diffusion of any toxic NO2. #chemistry #experiment #science #electrochemicalcell #education #physics #scienceexperiment #coppersulphate
