Annealing Star Polyelectrolytes Titration Curves

To experimentally monitor the ionization of weak PE stars, one can measure the variation of the pH in the solution of PE stars upon adding strong acid or strong base. 

The degree of neutralization of the PE macroion can be calculated from the added amount of acid or base in relation to the detected pH. The apparent pAa (or pAlb) values can be found from the pH that corresponds to the degree of neutralization of a = 0.5.
