WebNitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold (III) ions ( Au3+ ). The hydrochloric acid provides a ready supply of chloride ions ( Cl− ), which … 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: WebThe reaction of solid iron (II) hydroxide and aqueous nitric acid is represented by the balanced formula equation.
