R
F
has plenty of 0.1
Using the pKa of acetic acid/sodium acetate 4.74 and the equation pH = pKa + log[base]/
[acid] How many mL of sodium acetate will she need? What is the final
concentration (in molarity) of the sodium acetate and the acetic acid. Use this
information to prove that the student has correctly calculated the volume of sodium
acetate that she needs.
5. Calculate the concentrations of H+, HCO3-, and CO3-2- in a 0.025M H₂CO3 solution
6. Compare the strengths of the following pairs of acids:
a. HF and HBr
b. H2SO4 versus H2SeO4, and H3PO4 versus H3AsO4 and C1O4H versus CIO2H (trends
with oxoacids)
7. Calculate the pH of 0.10M Ammonia (NH3) Repeat the calculation after addition of 25
mL of 0.1M HCI.
