WebAug 1, 2012 · The Henderson–Hasselbalch Equation Equation Describes the derivation of pH as a measure of acidity in biological and chemical systems. The equation is also useful for estimating the pH of a buffer solution. it is widely used to calculate the isoelectric point of proteins( point at which protein neither accept nor yield proton) .

WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that. how to add css property in javascriptWebIMPORTANT Edit 2: It was pointed out to me that there was a slight mistake in my equation for Henderson-Hasselbalch.
