Nitric acid is an inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] . The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.

1977年8月1日 · We have made calorimetric measurements leading to apparent molar heat capacities at constant pressure of dilute aqueous solutions of HNO 3, NaNO 3, and KNO 3 at 298.15 K. Results have been used to derive Cp, φo = −72.1 J K −1 mol −1 for HNO 3 (aq), Cp, φo = −28.9 J K −1 mol −1 for NaNO 3 (aq), and Cp, φo = −59.8 J K −1 mol −1 for KNO 3 (aq).
