Nitric acid is a highly corrosive mineral acid. You can see that nitrogen is at the centre and one oxygen is double-bonded with the nitrogen, while the other two oxygen atoms are single-bonded. Conditions for Reaction to Occur: For the reaction between Ammonia and Nitric Acid to occur you need a balanced amount of each. It is also referred to as the spirit of nitre and aqua fortis. Nitric acid is produced by the oxidation of ammonia. Empirical Formula (Hill Notation) HNO 3. In this reaction, copper is oxidized while nitric acid is reduced to nitric oxide. 3.4 transfer prepared solution into a 100 ml volumetric flask by using a glass funnel. This reaction may give rise to some non-negligible variations in the vapor pressure above the liquid because the nitrogen oxides produced dissolve partly or completely in the acid. Air oxygen is used for the process of ammonia conversion. Hazard ... NITRIC ACID, other than red fuming, with at least 65%, but not more than 70% nitric acid . It's reactions vary on concentration of the nitric acid solution. Nitric acid is a very strong and corrosive mineral acid, also called aqua fortis or spirit of niter. Nitric acid is subject to thermal or light decomposition and for this reason it was often stored in brown glass bottles: . SG = ρ nitric acid / ρwater Note: Both densities need to be in the same unit as they will cancel each other and produce SG. In its pure form, it is colourless but as it gets older it turns into a yellow cast. PubChem Substance ID 24853516. Molecular Weight 63.01 . Nitric Acid, Chromium(3 ) Salt.
