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.
WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic.
