QUESTION:

Consider the following four titrations.

i. 100.0 mL of 0.10 M HCl titrated by 0.10 M NaOH

ii. 100.0 mL of 0.10 M NaOH titrated by 0.10 M HCl

iii. 100.0 mL of 0.10 M CH3NH2 titrated by 0.10 M HCl

iv. 100.0 mL of 0.10 M HF titrated by 0.10 M NaOH Rank the titrations in order of:

a. increasing volume of titrant added to reach the equivalence point.

b. increasing pH initially before any titrant has been added.

c. increasing pH at the halfway point in equivalence.

d. increasing pH at the equivalence point. How would the rankings change if \(\mathrm{C}_{5} \mathrm{H}_{5} \mathrm{~N}\) replaced \(\mathrm{CH}_{3} \mathrm{NH}_{2}\) and if \(\mathrm{HOC}_{6} \mathrm{H}_{5}\) replaced HF?
