Now that we have the pka, we can use it, along with the concentrations of the weak acid and its conjugate base, in order to solve for the ph of the solution. Ph = kₐ + log ( a⁻/ ha) ka is the acid dissociation constant. As we have seen above, the pk a gives an idea of the acidity and basicity of molecules, and is hence very useful in pharmaceutical, chemistry, biology and biochemistry fields. Ph=pka + log (b/bh +) now the ratio of unionized to ionized forms of the base can be written as.
