SKU: Y3A-PAB-7YZ Category:



Nitric acid (HNO3) is a highly corrosive and strongly oxidizing inorganic acid commonly used in a variety of industrial and laboratory applications. Nitric acid 70% is a solution of nitric acid in water, with a concentration of 70% nitric acid and 30% water. This product is commonly referred to as “concentrated nitric acid”.


Nitric acid is used for the production of fertilizers, nitration of organic compounds, and for the purification of metals such as gold and platinum. In the production of fertilizers, nitric acid is used to produce ammonium nitrate, which is a key ingredient in many fertilizers. In the nitration of organic compounds, nitric acid is used to introduce the nitro group (-NO2) into an organic molecule, producing a nitro compound.


In metallurgical processes, nitric acid is used to dissolve impurities from precious metals such as gold and platinum. When nitric acid is mixed with hydrochloric acid, it forms aqua regia, which is a powerful solvent for noble metals. This mixture is commonly used to dissolve gold in the refining process.


Nitric acid 70% is also used in the laboratory for the preparation of nitrate salts, the determination of metals and non-metals, and as a reagent in various chemical reactions. In chemical analysis, nitric acid is used to dissolve metals, such as iron and copper, in order to determine their concentration.


When handling nitric acid 70%, it is important to take appropriate safety precautions. Nitric acid is a strong irritant to the skin and eyes, and can cause chemical burns. Inhaling the fumes of nitric acid can irritate the respiratory system, and can cause coughing and difficulty breathing. It is recommended to wear protective gloves, eye protection, and a face mask when handling nitric acid 70%.


In addition to the safety precautions, it is important to store nitric acid 70% in a well-ventilated area, away from heat and ignition sources. The container should be labeled with the appropriate hazard warnings and kept tightly sealed when not in use. Nitric acid 70% should be stored in a cool, dry place, and should not be stored near flammable or combustible materials.
