How do you calculate pH from pKa?
pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid.
Is pH equal to pKa?
Remember that when the pH is equal to the pKa value, the proportion of the conjugate base and conjugate acid are equal to each other. As the pH increases, the proportion of conjugate base increases and predominates.
