1. A weak acid (benzoic acid) is titrated with a strong base such as sodium hydroxide. Determine the pH at the half equivalence point of the titration. The Ka of the weak acid is 6.3 x 10-5. 2.Calculate the pH of a buffer made from 0.6 M HNO2 and 0.5 M NaNO2. Ka = 4.5 x 10-5 pKa = 4.3 Answer with one digit after the decimal place (e.g. 2.1) Hint: HNO2 is a weak acid. NaNO2 forms the conjugate...

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...
