WebVideo transcript. - [Voiceover] Let's look at how to use a pKa table. Remember from general chemistry that pKa is equal to the negative log of the Ka. And the lower the pKa value the stronger the acid. pka values are used a lot in organic chemistry, so it's really important to become familiar with them. chuck berry piano sheet musicWebpKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be understood only if their pKa values are known.
