A sample of NH4Cl is prepared for titration by dissolving the salt in water, making 100.0 mL of solution. A second sample of NH₄Cl of identical mass is used to prepare 200.0 mL of solution. A solution of 0.10 M NaOH or 0.10 M HCl may be used to perform the titration.

a. Which solution, the 0.10 M NaOH or 0.10 M HCl, should be used to perform the titration? Justify your answer?

b. Compare the volume of titrant selected in part a that you would need to reach the equivalence point of the titrations for each of the samples.

c. Compare the pH of the two solutions at the equivalence point of the titrations (assume additive volumes).
