Nitric acid is used in the production of ammonium nitrate for fertilizers, making plastics, and in the manufacture of dyes. It is also used for making explosives such as nitroglycerin and TNT. When it is combined with hydrochloric acid, an element called aqua regia is formed.
Ammonia is a Lewis base because nitrogen has a lone pair of electron which can be donated to anyone and hence it acts as Lewis base. Lewis base is the species that mainly could donate one or more electron pairs. One of the best example is NH3 acts as lewis base as it has a lone pair of electrons on nitrogen.
Ammonia, also known as NH3, is a waste product made by your body during the digestion of protein. Normally, ammonia is processed in the liver, where it is changed into another waste product called urea. Urea is passed through the body in urine. High ammonia levels in the blood are most often caused by liver disease.
Definition of fuming nitric acid
: concentrated nitric acid containing dissolved nitrogen oxides prepared as either a colorless to pale yellow or a red to brown corrosive poisonous liquid and used especially as a nitrating agent and as a powerful oxidizing agent (as in rocket propellants)Ammonia is very soluble in water (it is the most soluble gas) where it reacts to form ammonium ions and hydroxide ions at appropriate pH. A saturated solution is highly corrosive and contains about 0.31 kg ammonia per kg solution at 25 °C, and has a density of about 0.88 g ˣ ml-1 (> 13 M).
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V2O5) is now preferred.
Using ammonium nitrate in gardens and large scale agricultural fields enhances plant growth and provides a ready supply of nitrogen from which plants can draw. Ammonium nitrate fertilizer is a simple compound to make. Anti- caking agents are also added to the fertilizer.
Production. The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: HNO3 + NH3 → NH4NO. Ammonia is used in its anhydrous form (i.e., gas form) and the nitric acid is concentrated.
Under normal handling conditions, ammonium nitrate is not harmful. However, inhalation of high concentrations of ammonium nitrate dust can cause respiratory tract irritation. Symptoms may include: coughing, sore throat, shortness of breath, or even suffocation.
DESCRIPTION: When ammonium nitrate is dissolved in water it feels cold, which indicates an endothermic reaction. Ammonium nitrate dissolves in water with an endothermic reaction, a chemical reaction that consumes heat rather than releasing it. Ammonium nitrate consists of ionic bonds packed tightly together.
Ammonium nitrate isn't acid but a salt but it's solution is acidic because of it being a salt of weak base(ammonium hydroxide) and strong acid(nitric acid).
Keep in mind, though, that you can buy ammonium nitrate as a pure chemical; alternatively, you can collect it from instant cold packs or some fertilizers more easily and inexpensively than making it yourself.
Because of its danger and potential use by terrorists, ammonium nitrate is subject to strict regulation in most places. In 2011, according to NBC News, the Department of Homeland Security established rules limiting the sale of the compound, which is also used as an explosive in the construction and mining industries.
Ammonia is a weak base because its nitrogen atom has an electron pair that readily accepts a proton. Also, when dissolved in water, ammonia acquires hydrogen ions from water to produce hydroxide and ammonium ions. It is the production of these hydroxide ions that imparts ammonia its characteristic basicity.
Ammonium nitrate can also be used as a good plant fertilizer; however it is far better suited to controlling acidic soil. Ammonium nitrate is the chemical compound of nitric acid and ammonia. 2. Ammonium sulphate is an inorganic composite of nitrogen and sulphur.
Industry sources
Released from industries producing, using or handling nitric acid, for example chemical plants, metal, electronic, printing, glass, rubber and plastics plants and industries. Where ever very high temperature combustion takes place in the atmosphere in the presence of nitrogen, oxygen and water.pH of Common Acids and Bases
| Acid | Name | 1 mM |

To Remove Nitric-Acid Stains
Nitric-acid stains can be removed from the hands by painting the stains with a solution of permanganate of potash, and washing off the permanganate with a 5 per cent solution of hydrochloric (muriatic) acid. After this wash the hands with pure castile soap.Table 7: Alkalis and acids frequently found in household products

Nitric Acid. Nitric acid (HNO3) is an extremely important chemical used in the manufacture of fertilisers and explosives. It is made from ammonia by the Ostwald Process (developed in 1902 by the German chemist Wilhelm Ostwald, who got the Nobel prize in 1909).
Nitric acid takes yellowish brown colour due to the presence of dissolved nitrogen dioxide. Nitric acid slowly decomposes even at room temperature, specially in the presence of sunlight. Liberated nitrogen dioxide dissolves in the acid and gives ayellow colour.
Nitric acid is an extremely corrosive acid capable of causing severe chemical burns very rapidly. If nitric acid mists are inhaled, health risks include corrosion of mucous membranes, delayed pulmonary edema, and even death. Contact with eyes can cause permanent cornea damage.
An Explosive Beginning
For example, nitroglycerin (the explosive component of dynamite) is made by adding nitric and sulphuric acids to glycerol under very carefully controlled conditions. Nitric acid is also used as an oxidising agent in the manufacture of nylon.Aqua regia is a mixture of nitric and hydrochloric acids. It takes its name from its ability to dissolve gold, which is sometimes referred to as the royal metal. Only the acid solution of aqua regia can dissolve the higher karats of gold (the third equation).
Ammonia is manufactured industrially by Haber's process. A mixture of dry nitrogen and hydrogen gases in the ratio of 1:3 by volume is compressed to about 200 to 300 atm and passed over iron catalyst at a temperature of about 723 k to 773 k. Ammonia being formed is continuously removed by liquefying it.
Nitric acid is prepared in the laboratory by heating a nitrate salt with concentrated sulphuric acid. Vapours of nitric acid are condensed to a brown liquid in a receiver cooled under cold water.
This oxidation reaction creates nitric oxide. In order to convert as much of the ammonia as possible, the process is carried out under pressure with a platinum-rhodium catalyst. The nitric oxide goes through another oxidation process to create nitric dioxide, which is mixed with water to create nitric acid.
The Ostwald process is used to produce nitric acid. It is reacted with oxygen and water using a platinum catalyst to produce nitric acid. The reaction is exothermic.
Greetings! Catalyst used in Ostwald process is Platinum. During ostwald process ammonia is converted to nitric acid in 2 stages.
The steps involved in the manufacture of sulphuric acid by contact process are as shown: (1) Sulphur (or iron pyrites) are burnt in air to form sulphur dioxide. (2) Catalytic oxidation of sulphur dioxide to sulphur trioxide. (3) Sulphur trioxide is dissolved in 98% sulphuric acid to form oleum (fuming sulphuric acid).
It is an oxidizing acid that can dissolve most metals to form soluble metal nitrates. Most metals and alloys are oxidized by nitric acid; however, gold and platinum are not oxidized and some metals are passivated when attacked by concentrated nitric acid.
Pt/ Rh is a well knitted guage with Pt and Rh alloy. it is used as a catalyst such as Ostwald process for the manufacture of nitrogen monoxide by the combustion of ammonia cause of high temperatures.
