The pka of a weak acid is useful for identification of an unknown acid because it is a constant (as long as temperature remains the same). When a weak acid is titrated with a strong base, the pka of the weak acid equals the pH at the half-equivalence point. A 0.3210 g sample of weak monoprotic acid is delivered into laboratory glassware. It will be used for titratation against 0.1254 M NaOH. If the molar mass of the weak acid...
