Ostwald’s process is a process by which the nitric acid can be obtained in three degrees. In the first stage ammonia and oxygen react (with platinum-rhodium as a catalyst), whereby the nitrogen monoxide and water emerge
In the second stage nitrogen monoxide reacts with oxygen whereby nitrogen dioxide emerges
and in the third stage nitrogen dioxide dissolves in water, in the presence of air, giving the nitric acid
