Heating nitric acid

WebCommercially available nitric acid is an azeotrope with water at a concentration of 68% HNO 3, which is the ordinary concentrated nitric acid of commerce. This solution has a boiling temperature of 120.5°C/760 mm. Two solid hydrates are known – the monohydrate (HNO 3 ·H 2 O) and the trihydrate (HNO 3 ·3H 2 O). Web1 de ene. de 2024 · The digestion process is also limited by the boiling point of the acid or acids used. In multi-acid digestion, the most volatile acids boil away first followed by the next most volatile [7]. The boiling point of nitric acid, aqua regia and HNO 3: H 2 O 2 (1:1) are 120, 108 and 85 °C respectively.
