Write balanced equations and name the products formed when:(a) Sodium hydrogen carbonate is added to nitric acid(b) cupric oxide reacts with nitric acid(c) zinc reacts with dilute nitric acid(d) concentrated nitric acid is heated |
Answer» (a) When Sodium hydrogen carbonate is added to nitric acid sodium nitrate, carbon dioxide and water is formed. NaHCO3 + HNO3 → NaNO3 + H2O + CO2 (b) When Cupric oxide reacts with dilute nitric acid, it forms Copper nitrate. CuO + 2HNO3 → Cu(NO3)2 + H2O (c) Zinc reacts with nitric acid to form Zinc nitrate, nitric oxide and water. 3 Zn + 8HNO3 → 3Zn(NO3)2 + 4H2O + 2NO (d) 4HNO3 → 2H2O + 4NO2 + O2 |
