The Ostwald Process Zora Hudson 07.05: Le Châtlier’s Principle History Wilhelm Ostwald was born in 1853 in Latvia and developed the Ostwald Process in 1902, for which he won a Noble Peace Prize in 1909. The Ostwald Process has proved to be a very important development because it provides a simply way to produce nitric acid, which is an essential ingredient for many modern products. Nitric acid is used in almost all nitrogen containing compounds, including explosives, making Ostwald’s discover instrumental in the German’s development of explosives. The Ostwald Process is used in both industrial and health fields… ▪ Nitric acid is the primary ingredient in fertilizers. Uses ▪ Nitric acid is also used in the manufacture of dyes and organic chemicals, making is especially useful in pharmaceuticals. ▪ Nitric acid is used to build explosives, due to its reaction with certain chemical compounds. ▪ The Ostwald Process is a chemical process used in modern chemistry to make nitric acid (NHO3) The Process ▪ Chemists usually heat a platinum gauze as a catalyst for this reaction. How is NHO3 created? ▪ Ammonia is heated with oxygen to produce nitric oxide: 4NH3 + 5O2 → 4NO (g) + 6H2O (g) Due to the fact that extreme heat is released duringthis process, the reaction is exothermic. ▪ Nitric oxide is combined with oxygen to produce nitrogen dioxide: 2NO (g) + O2 (g) → 2NO2 (g) ▪ Nitrogen dioxide is absorbed in water to create nitric acid: 3NO2 (g) ...
