WebbFor example, the Ka constant for acetic acid (CH 3 COOH) is 0.0000158 (= 10 -4.8 ), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid. WebbCalculating pH for Titration Solutions: Strong Acid/Strong Base A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH (the titration curve is shown in Figure 14.18).Calculate the pH at these volumes of added base solution:

"WebbThe values of \(pK_a\) and \(pK_b\) are given for several common acids and bases in Table 16.5.1 and Table 16.5.2, respectively, and a more extensive set of data is provided in Tables E1 and E2. Because of the use of negative logarithms, smaller values of \(pK_a\) correspond to larger acid ionization constants and hence stronger acids. " - Theoretical pka value of acetic acid
