What compounds nitric acid?
Nitric acid is made by reaction of nitrogen dioxide (NO2) with water. The net reaction is: 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.
What is the reaction of laboratory preparation of nitric acid?
Nitric acid is prepared by the reaction of conc. sulphuric acid with potassium or sodium nitrate.
How nitric acid is prepared?
Nitric acid is prepared in the laboratory by heating a nitrate salt with concentrated sulphuric acid. Dissolved oxides of nitrogen are removed by redistillation or blowing a current of carbondioxide or dry air through the warm acid.
What is Ostwald process in chemistry?
The Ostwald process is used to produce nitric acid. Ammonia is the feedstock for this reaction. It is reacted with oxygen and water using a platinum catalyst to produce nitric acid. The reaction is exothermic.
What is the common name of nitric acid?
aqua fortis
Nitric acid (HNO3), also known as aqua fortis (Latin for “strong water”) and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water.
What is the structure of nitric acid?
The chemical formula of nitric acid is HNO3 and it is made up of one hydrogen atom, one nitrogen atom, and three oxygen atoms. Its chemical structure indicates that it is a planar molecule and it has two resonance forms. Nitric acid is most commonly used in the production of fertilizer.
How is nitric acid detected in the laboratory?
The nitrate ion can easily be identified by heating copper turnings along with concentrated sulfuric acid. Effervescence of a brown, pungent gas is observed which turns moist blue litmus paper red. Nitric acid then reacts with the copper turnings to form nitric oxide. Nitric oxide is thus oxidised to nitrogen dioxide.
How is nitric acid is manufactured by Ostwald’s process?
The Ostwald process converts ammonia to nitric acid and involves two steps. In step 1, ammonia is oxidized to form nitric oxide and also nitrogen dioxide. Then in step 2, the nitrogen dioxide that was formed is absorbed in water. This in-turn forms nitric acid.
What is Ostwald’s process explaining the process and conditions?
The Ostwald process is a chemical process used for making nitric acid (HNO3). Wilhelm Ostwald developed the process, and he patented it in 1902. The Ostwald process is a mainstay of the modern chemical industry, and it provides the main raw material for the most common type of fertilizer production.
What is the name of No?
Nitric oxide
Nitric oxide/IUPAC ID
What is the name of the compound HBrO3?
Bromic acid
Bromic acid | HBrO3 – PubChem.
What is the concentration of nitric acid?
Ordinary nitric acid is about 68% with a density of 1.4. At this concentration it forms a constant boiling mixture (boiling point 120°C). Concentrated nitric acid is about 98% and has a density 1.51.
Why is nitric acid important for science students?
Nitric acid is one of the most important compounds that is used in the manufacture of many industrial as well as commercial products. Thus, it is crucial for science students to study about nitric acid and gain proper knowledge early on.
What is the name of the nitric acid solution?
Solution 1: (a) Aqua fortis: Nitric acid is called aqua fortis. Aqua fortis means strong water. It is so called because it reacts with nearly all metals. (3 parts by volume) gives a mixture called aqua regia.
Can a concentrated sulphuric acid replace conc.nitric acid?
(b) Concentrated hydrochloric acid cannot replace Conc. Sulphuric acid for the preparation of nitric acid because hydrochloric acid is volatile acid and hence nitric acid vapours will carry HCl vapours. (c) Conc. Nitric acid prepared in the laboratory is yellow in colour due to the dissolution of reddish brown coloured nitrogen dioxide gas in acid.
How can nitric acid be concentrated beyond 68%?
At higher temperature nitric acid may also decompose. Nitric acid cannot be concentrated beyond 68% by the distillation of dilute solution of HNO3. State the reason. Nitric acid forms a constant boiling mixture with water containing 68% acid. This mixture boils constantly at constant boiling point without any change in its composition.
