Product Details

Nitric acid

Nitric acid, or lye, is a very strong mineral acid with the formula HNO3, and is a colorless liquid in high purity, and after a while, due to decomposition into nitrogen oxides and water, it gradually turns yellow.

Pure nitric acid melts at a boiling point of -41.6 degrees Celsius, producing a colorless liquid. Of course, depending on the temperature and degree of light irradiation, the color spectrum of nitric acid can change from yellow to reddish brown, and the change is a result of the decomposition of nitric acid according to the reactivity 4HNO3 → 2H2O + 4NO2 + O2. Due to the reactions, the containers containing nitric acid are always under controlled pressure.

Nitric acid is flammable when mixed with water and forms an azeotropic solution whose boiling point is 121.9 degrees Celsius, which contains 68.7% by weight of HNO3.

In the chemical market, nitric acid is sold with concentrations and purity of 40%, 68%, 86% and up to 96%. Tabriz Chemical Company, a supplier of various chemicals, supplies all the requested purity of nitric acid.

Nitric acid concentration greater than 86% is known as fuming nitric acid, and nitric acid with a concentration of more than 95% is known as fuming nitric acid. These acids are used as oxidizers in rocket fuel.

What is Nitric Acid?

Nitric acid (Nitric acid), with the chemical formula HNO3 and other names such as lye and lye, is a highly corrosive mineral acid. It exists as a colorless liquid with yellow vapors and a pungent odor; but due to the decomposition of this acid, it turns yellow after a while. This compound is very corrosive and toxic and causes severe skin burns. It is used as a strong oxidizing agent, a common reagent in laboratories, in the production of explosives and fertilizers. This substance is a strong acid; because the more the acid is dissociated in an aqueous solution, the stronger the acid is. This substance is completely decomposed in water by breaking down hydrogen ions and nitrate ions.

Edible nitric acid:

The edible form of this acid is used in the food industry. In this industry, this substance is used to prevent bacterial growth, stabilize the color of red meat, and as a preservative. This compound is an effective ingredient in preserving meat products such as sausages, hot dogs, hamburgers, etc.

 

Use of nitric acid in the food industry

 

In some cases, if the color of the purchased meat is very red, it is because a large amount of this acid has been added to the meat.

Production method:

This substance is made from the reaction of nitrogen dioxide with water and its formula is as follows:

NO2+2H2O→2HNO3+NO+NO2+H2O4

The net reaction to Formula:

NO2+H2O→2HNO3+NO3

Usually the acid produced by the reaction is reoxidized by oxygen in the air to produce additional N2 dioxide. The bubbling of nitrogen dioxide through hydrogen peroxide can help improve the performance of the acid.

2NO2+H2O2→2HNO3

Laboratory preparation method:

Usually the more volatile acid is separated from its salt by the less volatile acid, and this is a basic principle in the laboratory preparation of this substance. Nitric acid is more volatile than sulfuric acid, so it is separated from metal nitrates by sulfuric acid. To produce this product in the laboratory, 50 grams of potassium nitrate are poured into a round-bottomed flask along with 25 ml of concentrated sulfuric acid and it is heated to 200 degrees Celsius. The equation for this reaction is:

KNO3+H2SO4 → KHSO4+HNO3

In another method in laboratories, this acid can also be produced from the thermal decomposition of copper nitrate. Here, nitrogen dioxide and oxygen gases are produced and then passed through water. The equation for this reaction is as follows:

2Cu(NO3)2→2CuO+4NO2+O2

Following the Ostwald process:

2NO2+H2O→HNO2+HNO3

Another method involves reacting equal moles of any nitrate salt, such as sodium nitrate, with sulfuric acid and distilling the mixture at the boiling point of this acid at 83 °C.

Reactions:

The reaction of nitric acid with potassium sulfite produces potassium sulfate. Of course, the other products of this reaction are nitrogen dioxide and water.
