Consider the titration curve in Exercise 89 for the titration of Na2CO3 with HCl.
a. If a mixture of NaHCO3 and Na2CO3 was titrated, what would be the relative sizes of V1 and V2?
b. If a mixture of NaOH and Na2CO3 was titrated, what would be the relative sizes of V1 and V2?
c. A sample contains a mixture of NaHCO3 and Na2CO3. When this sample was titrated with 0.100 M HCl, it took 18.9 mL to reach the first stoichiometric point and an additional 36.7 mL to reach the second stoichiometric point. What is the composition in mass percent of the sample?
