Nitric acid 98% have? Commercially available concentrated nitric acid content of about 65%. Fuming nitric acid: colorless to yellowish or slightly brown clear liquid. Department of concentrated nitric acid containing dissolved nitrogen dioxide. 90% to 100% nitric acid. Emit nitrogen dioxide, nitrogen tetroxide of red and yellow smoke. Miscible with water. The relative density by increasing free nitrogen dioxide increases. Concentrated nitric acid containing nitrogen dioxide by 7.5 percent relative density (d204) of 1.526, containing nitrogen dioxide by 12.7% relative density (d204) 1.544. Strong oxidation and corrosion, do not come into contact with the oxide. Avoid contact with skin. Wound approach approach nitric acid burn wounds after burns after nitric acid burns, as with the general, mainly based on the degree of the depth of the wound to be. 1. shallow wound treatment: I degree burns primarily relief of pain and injury protection forgo; superficial II degree burn wounds in addition to pain, the main is to prevent infection, nitric acid, its early healing. It can be exposed, semi-exposed or bandaged. The wound can be applied in the West drugs. If infection, the use of potassium nitrate, generally can be rinsed, wet methods to clean the wound, systemic use of antibiotics to control the infection. 2. The depth of the wound treatment: possible exposure therapy, for dressing, usually not more than 3-5 days. 10% or less of the small area deep burn, the body in stable condition, should seek early an operation to scab (cut, cut crust), autologous skin coverage. Small area burns no shock, could immediately after injury escharectomy, if not easy to ascertain the depth of shock or when it should be corrected after the shock were basic. Burns over 30% who should normally after 48 hours after the injury, and systemic hemodynamics to be re-excision and when the situation stabilized. But if there is a good heart, lungs and hemodynamic monitoring, and pre-injury patient better physique, nitric acid droplets, but also quickly add volume after early excision. Surgery can be performed once or several times, usually cut area to 15% -30% is appropriate everytime. In a good hemodynamic monitoring, and even the degree III around 60% of a total removal of the wound.
