Example 1
Find the concentration of acetic acid in vinegar if 21.6 milliliters of 0.20 M
NaOH is needed to titrate a 25-milliliter sample of the vinegar.
Solution
Using the equation Macid × Vacid = Mbase × Vbase, we have
Another type of titration problem involves a solid and a titrated solution.Example 2
A solid mixture contains NaOH and NaCl. If 10.0 milliliters of 0.100 M HCl is
required to titrate a 0.100-gram sample of this mixture to its end point, what is the
percent of NaOH in the sample?
Solution
Since
then
