The reaction between copper and concentrated nitric acid:
Cu + 4HNO₃ → Cu(NO₃)₂ + 2H₂O + 2NO₂
The reaction between copper and dilute (2M - 6M) nitric acid:
3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 4H₂O + 2NO
Cu + 4HNO₃ → Cu(NO₃)₂ + 2H₂O + 2NO₂
The reaction between copper and dilute (2M - 6M) nitric acid:
3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 4H₂O + 2NO
