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 C5H5N replaced CH3NH2 and if HOC6H5 replaced HF?

- Calculating standard reaction free energy from standard reduction... Using standard reduction potentials from the ALEKS Data tab, calculate the standard reaction free energy AG° for the following redox reaction. Be sure your answer has the correct number of significant digits.

The pK of aniline is 9.37. Calculate the pH of the base solution after the chemist has added 184.2 mL of the HNO 3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added.
