The quantity pH, or "power of hydrogen," is a numerical representation of the acidity or basicity of a solution. To convert Ka into pKa, get out your calculator and find -log . . pKa is defined as the negative logarithm (-log) of Ka . 1.Use the equation Ka=10-pKa{\displaystyle Ka=10^{-pKa}} for this conversion. In other words, a low pKa indicates a strong acid and vice versa. Till i found this. For example, log8 is just log2+log2+log2 = 0.3*3. log9 = log3+log3.
