Question: In the figure below, titration curves for strong acid
with strong base and weak acid with strong base are shown. Compare
the shapes of these curves early in the titration for three
different cases: titration of a strong acid, titration of a weak
acid with a lower pKa, and titration of a weak acid with a higher
pKa. Discuss with the class why the titration curve for weak acids
increase more rapidly early in the titration than do stronger...

- Calculating the pH of a weak acid titrated with a strong base An analytical chemist is titrating 123.0 ml. of a 0.5100 M solution of nitrous acid (HNO,) with a 0.6900 M solution of NaOH. The pk of nitrous add 3.35. Calculate the pH of the acid solution after the chemist has added 74.18 ml of the NaOH solution to it. Note for advanced students you may assume the final volume equals the initial volume of the solution plus...

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...
