Dilution drives the pH value of an acidic or basic solution toward 7. The pH values of acidic solutions increase with dilution, while the pH values of basic solutions decrease with dilution. Continue Reading.
Effects of pH. Enzymes are affected by changes in pH. The most favorable pH value-the point where the enzyme is most active-is known as the optimum pH. This is graphically illustrated in Figure 14.Extremely high or low pH values generally result in complete loss of activity for most enzymes.ffects of pH. Enzymes are affected by changes in pH.
