What is the pKa of a Bronsted acid?

The pKa of a Bronsted acid provides a description of the tendency of the acid to donate a proton in an aqueous (water-based) solution. A lower pKa is associated with a stronger tendency to donate protons, and thus a stronger Bronsted acid. The pKa is calculated mathematically as the negative logarithm (base 10) of the equilibrium constant for dissociation of a proton from the acid in water.
