Solution: Nitric acid, a major industrial and laboratory acid, is produced commercially by the multistep Ostwald process, which begins with the oxidation of ammonia:Step 1. 4 NH3(g) + 5 O2(g) ⟶ 4 NO(g) +6 H2O(l) Step 2. 2 NO(g) + O2(g) ⟶ 2 NO2(g) Step 3. 3 NO2(g) + H2O(l) ⟶ 2 HNO3(l) + NO(g) What are the oxidizing and reducing agents in each step?
