WebThe buffer is a mixture of a weak acid and its conjugate base. The buffering capacity of a solution is determined using the Henderson-Hasselbalch Equation, and the closer the ratio of acid to conjugate base is to one the higher buffering capacity. A buffer also can consist of a weak base and its conjugate acid as well. pH = pKa + log ([A-] / [HA]) http://dissolutiontech.com/issues/202408/DT202408_A03.pdf
