Pka value of hno3
Nitric acid is normally considered to be a strong acid at ambient temperatures. There is some disagreement over the value of the acid dissociation constant, though the pKa value is usually reported as less than −1. This means that the nitric acid in diluted solution is fully dissociated except in extremely acidic solutions. The pKa value rises to 1 at a temperature of 250 °C. Nitric acid can act as a base with respect to an acid such as sulfuric acid: WebMar 25, 2024 · The Ka value of HNO3 is about 24. HNO3 is the chemical formula for strong nitric acid. The Ka value, also known as the acid dissociation equilibrium constant, is a …
