Explanation:

The nitrate ion can easily be identified by heating copper turnings along with concentrated sulfuric acid. Brown, pungent effervescence is observed which turns blue litmus red. ... Nitric acid then reacts with the copper turnings to form nitric oxide. Nitric oxide is thus oxidised to nitrogen dioxide.
