value for K b indicates that the base has dissociated to a greater extent. Weak acids are related to their conjugate weak bases. For a conjugate acid-base pair, the K a and K b are related by the following equation: K a • K b = K w = 1.00 x 10-14 (at 25 oC) In this experiment you will use a pH probe interfaced to a computer. The probe will need to be calibrated prior to use. This will be

The larger the value of Kb, the stronger the base, and the larger the value of Ka, the stronger the acid. By multiplying Ka by Kb, you receive the Kw, or the dissociation constant for water, which is 1.0 x 10^-14. When finding the Kb from the Ka, it is necessary to connect these various parts of the equation.
