Nitric acid technical 57% readily dissolves certain metals, whereas at a higher concentration the metals do not dissolve.
This property is used to clean pipelines from metal salts.
Nitric acid 57% is used in almost all industries.
For a human body, vapors of Nitric acid are dangerous - they damage the respiratory tract. Vapors are heavier than air more than 2 times, therefore in places of storage at a leak they will accumulate closer to a floor.
If it gets on the skin, it causes a chemical burn, while the skin becomes yellow.
Contact with organic can cause fire and even explosion.

Technical-grade nitric acid 57% is designed for tasks where a stable concentration, predictable oxidising activity and compliance with an industrial standard matter, but where the purity level of chemically pure, analytical grade or extra pure grade is not required. Unlike reagent grades, technical acid can have wider tolerances for impurities and grades, so when purchasing it is necessary to check the GOST, the mass fraction of HNO₃, the content of nitrogen oxides, the residue after ignition and appearance. Substituting a reagent grade with technical acid is only possible after agreement with the laboratory or process engineer.
Technical-grade nitric acid 57% is stored in tightly closed, chemically resistant containers, in a ventilated, unheated warehouse, separately from organic substances, reducing agents, alkalis, flammable materials and heat sources. The product fumes heavily in air and is a vigorous oxidiser, so it is important to prevent damage to canisters, spills and contact with incompatible substances. For a wholesale batch it is necessary to preserve the quality certificate, labelling, production date and take into account the guaranteed shelf life.
Technical-grade nitric acid 57% is diluted in a chemically resistant container, with stirring and temperature control. The acid is added to water in small portions, not the other way round, to reduce the risk of local overheating, splashing and vapour release. Before preparing the working solution, the required concentration is calculated, and the quality of the water and the condition of the container are checked. The operation is carried out in safety goggles or a face shield, acid-resistant gloves, protective clothing and with effective ventilation.
