Preparing a platinum catalyst for the Ostwald-Oxidation feat. aqua regia - Astral Chemistry
Ostwald process: Catalytic oxidation of ammonia for the production of nitric acid - Astral Chemistry
Make Nitric Acid from Nitrate Salts, two methods : Copper+HCl+Nitrate->NO2->HNO3 (weak H2O2 needed); Nitrate+H2SO4 distilled -> HNO3 - NurdRage
On peut faire de l'acide nitrique simplement en bullant du NO2 dans de l'eau, ou mieux de l'H2O2
