Using the titration curve below, determine the following: (type
or write neatly)
a) Is the analyte a strong acid, weak acid, or polyprotic acid?
What is the titrant (what kind of substance)? What do the dots on
the titration curve represent?
b) What is the ½ equivalency point of the titration? If
more than one ½ equivalency point exists, report the volume of
titrant and pH of each.
c) If the titration was performed with 0.30 M NaOH, what is the
concentration of the acid solution?
d) Using the table of pKa values for inorganic acids below: can
you determine which species was
the analyte? (Ignore pKa values in parentheses on the
table.)
