Cu → NO2 → HNO3 → Al (NO3) 3 → Al2 (SO4) 3
1) Cu + 4HNO3 → Cu (NO3) 2 + 2NO2 ↑ + 2H2O (substitution reaction);
2) 3NO2 + H2O → 2HNO3 + NO ↑ or 4NO2 + O2 + 2H2O → 4HNO3 (substitution reaction or compound reaction);
3) Al (OH) 3 ↓ + 3HNO3 → Al (NO3) 3 + 3H2O (exchange reaction);
4) 2Al (NO3) 3 + 3H2SO4 → Al2 (SO4) 3 + 6HNO3 (exchange reaction).
