WebThe equation for pH also shows why pH does not change by much in buffers. When the ratio between the conjugate base/ acid is equal to 1, the pH = pK a. If the ratio between the two is 0.10, the pH drops by 1 unit from pK a since log (0.10) = -1. If a ratio increases to a value of 10, then the pH increases by 1 unit since \log (10) = 1.
