WebAny time you have a buffer and the pH of your solution is equal to the pK_a of your buffer, you immediately know that the concentration of your acid and its conjugate base are the same. And this comes up a lot not just when you're talking about buffers by themselves, but also when you're doing titrations. WebpH = -log 10 [H +] The pH scale is a measure of hydrogen ion concentration that eliminates dealing with large powers of 10 and compresses a large range of concentrations onto a more convenient scale, between 1 and 14. At a high concentration of H ‑ (10 -1 M), the pH value is low, pH = 1.
