Herleitung der Formel pH = 1/2 (pKs - log c(HA)) über das MWG. 3 Varianten zur pH-Wert Berechnung.
In this video, I derive the formula pH = 1/2 (pKa - log c(HA)) using the law of mass action and a little math (powers, logarithms). In this context, you'll see that there are three ways to calculate the pH of a 0.1 molar acetic acid solution. The question also arises whether you should simply memorize this formula or consistently use the law of mass action to calculate pH. A user comment (shown in the video, but the user's name isn't mentioned) raised this question and prompted this video. Thank you! : ...
