Answer 2

Answer:

Talking about the reaction between copper and nitric acid, copper is oxidized by concentrated nitric acid to produce Cu2+ ions. The nitric acid is reduced to form nitrogen dioxide which is a poisonous brown gas with an irritating odour. Also, Cupric nitrate, Cu(NO3)2 is formed in this reaction.
