The pH of an acidic solution, therefore, must be less than 7.00. A basic solution, on
the other hand, will have a pH greater than 7.00. Figure 6.3 shows the pH scale
along with pH values for some representative solutions.
Tabulating Values for Ka and Kb A useful observation about acids and bases is that
the strength of a base is inversely proportional to the strength of its conjugate acid.
Consider, for example, the dissociation reactions of acetic acid and acetate.
