Ph of weak acids formula
Webb30 okt. 2006 · First question - Henderson-Hasselbalch equation works for strong acids too, although it can't be used for pH calculation, at least not in the same way as in the case of … WebbHowever, for weak acids, a quadratic equation must be solved, and for weak bases, a cubic equation is required. In general, a set of non-linear simultaneous equations must be solved. Water itself is a weak acid and a weak base, so its dissociation must be takent into account at high pH and low solute concentration (see amphoterism).
