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 measure of the acidity of a solution.
Strong acids, such as HNO3, have a Ka value that is greater than one. Acids with a Ka below one are known as weak acids, such as boric acid, which has a Ka value of about 7.3 x 10^(-10). The Ka value of an acid is related to its pH value through a logarithmic function. The Ka value describes how much an acid dissociates when made into an aqueous solution.
