Nitric acid
Nitric acid (formula: HNO3) is a strong acid, the water solution commonly known as nitrate or water or nitric acid. Pure nitric acid as a colorless liquid, the boiling point of 83 ° C, at-42 ° C condensation of colorless crystals, water immiscible, strong oxidation and corrosive. The solute mass fraction is 69.2%, the boiling point is 121.6 ℃ at atmospheric pressure, the density is 1.42gcm-3, about 16mol·L-1, the mass of solute is the mass concentration of the solution. Fraction is large enough (commercial concentration of up to 98% or more), known as fuming nitric acid, nitric acid is an important chemical raw materials. The acid anhydride of nitric acid is nitrous oxide (N2O5). ...
