formation of nitric acid in atmosphere in detail
Answers
Answer:
Nitric acid decomposes into water, nitrogen dioxide, and oxygen, forming a brownish yellow solution. It is a strong acid, completely ionized into hydronium (H3O+) and nitrate (NO3−) ions in aqueous solution, and a powerful oxidizing agent (one that acts as electron acceptor in oxidation-reduction reactions.
Nitric acid is made by reaction of nitrogen dioxide (NO2) with water. Or, shortened: 3 NO2 + H2O → 2 HNO3 + NO. Normally, the nitric oxide produced by the reaction is reoxidized by the oxygen in air to produce additional nitrogen dioxide.
Answer:
Ostwald process is one of the most common methods or chemical process used for the manufacturing of nitric acid. The process was developed in the year 1902 by a German chemist named Wilhelm Ostwald. He was later awarded the Nobel Prize in 1909 for his research.
Ostwald process has gained popularity over the years as it is the easiest way to produce nitric acid which is also widely used in many areas such as in the production of fertilizers as well as inorganic and organic nitrates or nitro compounds.
Usually, in the Ostwald process ammonia is transformed into nitric acid. Vanadium pentaoxide (V2O5) is often used as a catalyst during the processing of nitric acid in this method. There are several steps involved. We shall discuss them in detail below.
