Webb4 mars 2024 · A Crash Course on Logarithms. The “p” in pH, pKa, and pI denotes the negative logarithm, to base 10, of the parameter in question. Logarithms transform a nonlinear series of values into a linear series. E.g., the logarithm (to base 10) of, 10, 100, 1000, and 10,000 is 1, 2, 3, and 4 respectively. A quick math rule to jot down in your … WebbSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one.
