E. The 40.0 ml sample is to be titrated with 0.25 M NaOH until the endpoint is reached
Answer the following showing all work:
i
Determine the volume, in ml, of the 0.25 M NaOH that will be needed to reach
the endpoint.
ii.
Calculate the expected molar concentration of the propanoate ion (CH. CH. CO)
in the neutralized solution,
iii.
Determine the pH of the neutralized solution at the endpoint.
d. If the original 40,0 mL of the 0.10 M propanoic acid solution were used to make a
solution that was buffered at a pH of 4.89, what mass, in grams of sodium propanoate
(NaCHCH, COO) would need to be added?
