Description

Nitric acid (Nitric acid) is the colourless, transparent liquid with a pungent, unpleasant smell which is one of the major industrial chemical products.

Nitric acid is strong monobasic acid, in water solutions is totally dissociated on ions, the rastvorima in ethyl oxide mixes up with water in any ratios, however restrictedly.

As well as the majority of acids, nitric acid reacts with the bases, the main oxides, forcing out weak acids from their salts. Salts of nitric acid are called nitrates.

Nitric acid is the strong oxidizer dissolving all metals except for gold, rhodium, platinum, niobium, tantalum, iridium and zirconium, turning them into oxides or nitrates. Easily oxidizes elementary sulfur to sulfuric H2SO4 acid and phosphorus to phosphoric P2O5 anhydride.

Application

  • At production of mineral fertilizers;
  • in war industry (smoking - in production of explosives, as an oxidizer of rocket fuel, diluted - in synthesis of various substances including poisoning);
  • very seldom in the photo - diluted - acidulation of some tinting solutions;
  • in easel graphics - for etching of printing forms (ofortny boards, tsinkografichesky typographical forms and magnesian cliches);
  • At production of dyes and drugs (nitroglycerine)
  • in jewelry - the main way of definition of gold in gold alloy.

    The nitric acid which is not concentrated. GOST P 53789 - 2010.

    This standard extends to not concentrated nitric acid with a mass fraction of the nitric acid which is not exceeding 70% received by absorption of nitrogen oxides by water.
    On physical and chemical indicators, it is necessary that not concentrated nitric acid conformed to the requirements and norms given in the table.
    Name of an indicator Norm for a grade
    the highest The 1st The 2nd
    1. Appearance The transparent colourless or slightly painted in yellow color liquid without mechanical prinesy
    2. A mass fraction of nitric acid, % , on less 58,0 56,0 46,0
    3. A mass fraction of nitrogen oxides (in recalculation on N2O4), % , on more 0,07 0,10 0,20
    4. A mass fraction of the rest after calcinating, % , no more 0,004 0,020 0,050

    Not concentrated nitric acid is filled in in barrels, glass large bottles or polyethylene large bottles and canisters, and also in densely closed vessels made of stainless steel.
    it is necessary that the container was tight, dry and pure.
    For a product with a mass fraction of nitric acid more than 55% the admissible period of operation of a polymeric container makes no more than two years from the date of production.
    Glass large bottles have to be made of the dark glass or colourless glass having a light - protective covering or are wrapped up by lightproof paper.

    Not concentrated nitric acid is transported:
    - by rail, filling capacity according to rules of transportations in special tanks from acidproof materials of the consignor or consignee;
    - motor transport - in tanker trucks or densely closed stainless steel vessels;
    - packed into the barrels, canisters and large bottles placed in boxes - by rail in the covered cars car sendings, considering requirements of specifications of placement and fastening of freights in cars and containers;
    - the motor or water transport in barrels (capacities), polyethylene canisters, glass large bottles placed in polyethylene drums or boxes in the covered containers.

    Precautionary measures

    Nitric acid - nonflammable flammable liquid which is an oxidizer, contacting to a set of combustible materials causes their self - ignition.
    By production and storage of nitric acid, it is very important to follow fire safety regulations.
    Nitric acid beyond all bounds being dissolved in water, generates heat, it is hygroscopic, on extent of impact on a human body belongs to moderately dangerous substances (the 3rd class of danger).
    The Threshold Limit Value (TLV) of vapors of nitric acid in air of a working zone makes 2 mg/m3.

    Working with nitric acid, it is necessary to provide workers with special clothes, footwear with protective properties, means of protection of hands - rubber kislotozashchitny mittens and individual means of protection of respiratory organs and sight.
