When nitric acid is concentrated, the equation for the reaction is:
Cu(s) + 4HNO₃(aq) → Cu(NO₃)₂(aq) + 2H₂O(ℓ) + 2NO₂(g)
When nitric acid is dilute to moderately concentrated, the equation for the reaction is:
3Cu(s) + 8HNO₃(aq) → 3Cu(NO₃)₂(aq) + 4H₂O(ℓ) + 2NO(g)
When nitric acid is very dilute, there will be no reaction between copper and very dilute nitric acid.
