Chemistry

A pH 3.30 buffer is prepared from iodoacetic acidICH2COOH (pKa = 3.175), and sodiumiodoacetate, ICH2COO-Na+ . Ifionic strength of the buffer solution must not exceed 0.200 M, whatare the maximum concentrations of the two components that could beused?

What volume of KOH (conc = 1.850 M), could be added to 50.00 mLof the buffer solution of part (a), before the pH would increase to4.000?
