Abstract:
Recently, dynamic approach has been applied to determine the steady state concentrations of multiple ionic
species present in complex buffers at equilibrium. Here, we have used the dynamic approach to explicitly model
the pH profiles of biologically relevant phosphate buffer and universal buffer (a mixture of three tri-protic acids
such as citric acid, boric acid and phosphoric acid). The results from dynamic approach are identical to that of
the conventional algebraic approach, but with an added advantage that the dynamic approach, allow for the
modelling of complex buffer systems relatively easy compared to that of algebraic method.
