The result of the incomplete ionization of a weak acid or weak base is
the conjugate acid or conjugate base contributes towards the pH of the solution
neutralization occuring at a pH slightly lower or higher than 7
This part of an electrochemical cell is oxidized, thus attracting anions from the solution.
