Witryna6 maj 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 … Witryna16 mar 2024 · The pOH is a similar measurement to the pH and correlates to the concentration of hydroxide ions in a solution. The formula for the pOH is: pOH = -log10([OH-]) In specific conditions (aqueous solutions at room temperature), we can define a useful relationship between pH and pOH: pH = 14 - pOH
