The Ostwald process is used in the chemical industry to produce nitric acid. It involves two stages: oxidation of ammonia to form nitric oxide and water, and oxidation of nitric oxide to form nitrogen dioxide which is absorbed in water to form nitric acid. The process was patented by Wilhelm Ostwald in 1902 and it is closely associated with the …
Equipment must be carefully maintained to avoid corrosion. Acid spills are contained using materials such as earth, clay or sand, and then. ... The Ostwald process involves the oxidation of nitrogen, through a series of steps, from its. lowest oxidation state to its highest. Starting with ammonia ( NH 3 - oxidation number of N ...
The Ostwald process is a series of three reactions used for the industrial production of nitric acid from ammonia. If NO is not recycled, how many moles of NH3 are consumed per mole of HNO3 produced? Nitric acid, a major industrial and laboratory acid, is produced commercially by the multistep Ostwald process, which begins with the oxidation of ...
Nitric acid is produced industrially through a multistep reaction process known as Ostwald process. The purpose of this simulation was to observe the thermodynamic properties of the process.
Ostwald Process IntroductionIndustrially, nitric acid is made by the catalytic oxidation of ammonia over heated platinum. Oxidising ammonia produces oxides of nitrogen which can then be dissolved in water to produce nitric acid.ReactionInitially, nitrogen(II) oxide will be formed from the catalytic oxidation of ammonia using the transition metal …
