Re: Sodium Nitrate?? Nitric Acid??
Don't bother trying to make Nitric Acid.
Just purchase some ACS Grade from your local chem supply. It isn'y a watched precursor, and won't be suspect.
6671. Nitric Acid.
Aquafortis; Salpetersure (German). HNO3; mol wt 63.01. H 1.60%, N 22.23%, O 76.17%. Usually produced by the catalytic oxidation of ammonia. Reviews of

Colorless liq. Fumes in moist air. Characteristic choking odor. d425 1.50269. mp -41.59 deg. Monohydrate, mp -37.68 deg. Trihydrate, mp -18.47 deg. Heat of fusion:
2.503 kcal/mole. Heat of infinite dilution (298.1 degK): -7971 cal/mole. bp760 83 deg. With water it forms a negative azeotrope (min vapor press. max bp), so-called
constant boiling acid at 68% HNO3, bp 120.5 deg, d420 1.41. The oxide-free acid, diluted with an equal vol of water, does not discolor drops of 0.1N KMnO4. Colorless
100% acid cannot be stored in the presence of light without formation of NO2 which produces the discoloration. Stains woolen fabrics and animal tissue a bright
yellow. In the presence of traces of oxides it attacks all base metals except Al and special Cr steels which become passivated. Strong, monobasic acid. Oxidizing
agent. Reacts violently with alcohol, turpentine, charcoal, organic refuse. Nitric acid concentrated is a water soln contg 70-71% HNO3. Density of aq solns: d420

Caution: Potential symptoms of overexposure are irritation of eyes, mucous membranes and skin; delayed pulmonary edema, pneumonitis and bronchitis; dental
erosion. See NIOSH Pocket Guide to Chemical Hazards (DHHS/ NIOSH 90-117, 1990) p 160. See also Clinical Toxicology of Commercial Compounds, R. E.

USE: Manufacture of inorganic and organic nitrates and nitro compounds for fertilizers, dye intermediates, explosives and many different organic chemicals.
Pharmaceutic aid (acidifier).
THERAP CAT (VET): Cauterizing agent (for warts).
