WebMay 6, 2024 · The International Union of Pure and Applied Chemistry (IUPAC) has a slightly different pH scale that is based on electrochemical measurements of a standard buffer solution. Essentially, the definition uses the equation: pH = -log a H+. where a H+ stands for hydrogen activity, which is the effective concentration of hydrogen ions in a solution. WebAug 13, 2024 · The buffer capacity measures the resistance of a buffer to pH change on the addition of OH – ions (a base). We can give it in an equation as follows: β = dn /d (pH) where β is buffer capacity, dn is an infinitesimal amount of added base, and d (pH) is the resulting infinitesimal change in pH.
