WebbNitric acid is a strong oxidant for wet and dry oxidation of organic samples for metal analysis. it helps in the ionization of samples for easier detection during spectrophotomeric analysis. it... 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: toefl cameroon
