The number of electrons in the molecule nitric nitrogen highest valence (+5) and therefore has a strong oxidation of nitric acid, and its reduction product due to different concentrations of nitric acid changes, generally speaking, the higher the concentration of nitric acid, nitric acid per molecule obtained The less factory food grade nitric acid, concentrated nitric acid reduction product mainly nitrogen dioxide, nitric oxide in dilute nitric acid is mainly nitric acid, more dilute nitric acid can be reduced to nitrous oxide, nitrogen, ammonium nitrate, etc., to be noted that the present nitric acid plant quality, but the advantages of the above product superior grade nitric acid, in fact, as the reaction proceeds, the concentration of nitrate decreased, all reduction products are likely to occur. Storage: Store in a cool, ventilated warehouse. Away from fire and heat. Storage temperature should not exceed 30 ℃. Keep container closed. Should be stored separately with oxidants, acids, alkali metals, amines, avoid mixing reservoir. Explosion-proof lighting, ventilation facilities. Prohibit the use of mechanical equipment and tools easy to produce sparks. Storage areas should be equipped with spill response equipment and materials suitable host.
