De Henderson-Hasselbalchvergelijking negeert het feit dat in de definitie van de pH de negatieve logaritme van de chemische activiteit van protonen genomen wordt en niet de concentratie ervan: De gemaakte benaderingen werken minder goed bij: • sterkere zwakke zuren en sterkere zwakke basen. Voor sterkere zwakke zuren zal de aanname dat de ionisatie van het zuur praktisch geblokkeerd wordt door de aanwezigheid van de geconju… WebLimitations.

WebIMPORTANT Edit 2: It was pointed out to me that there was a slight mistake in my equation for Henderson-Hasselbalch. It was written as pKa - log (base/acid) instead of pKa + log (base/acid). I've updated the link. If there are any other mistakes (hopefully there aren't), please point them out to me so I can make the necessary changes. can r422d be mixed with r22Web30 okt. 2024 · La escala de pH fue introducida en 1909 por otro danés, Sørensen, y en 1912, Hasselbalch publicó mediciones del pH de la sangre.
