We get the following result. Now, let's actually use a simple rule that we know for mathematics. So in mathematics, we learn that if we take the log of the product of two values, a and B, then by the laws of logs, that is equal to log of A plus log of B. So if we look at the following expression, the right side, let's suppose that this the concentration of H plus is A and the ratio of the conjugate base to its assets. So A to ha is equal to the B value. So log of a, B is equal to.
