Q:

What is the ka value of HNO3?

A:

Quick Answer

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.

Full Answer

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.
