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. Webtetrabutylammonium hydroxide (TBAH) as the base. As an example, the plot obtained for compound 1 with TBAH is shown in Figure€3. The derived pKa' values, along with the Hammett σp-constant for each R-substituent are presented in Table€1. The method was validated with 1-naphthol, for which the experimental pKa value is reported as 9.30 [32,33].
