An analytical chemist is titrating 239.5 mL of a 1.000 M solution of propionic acid (HC,H,CO, with a 0.2500 M solution of NaOH. The pK, of propionic acid
is 4.89. Calculate the pH of the acid solution after the chemist has added 768.2 mL of the NaOH solution to it.
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added.

An analytical chemist weighs out 0.118 g of an unknown triprotic acid into a 250 mL volumetric flask and dilutes to the
mark with distilled water. She then titrates this solution with 0.1100M NaOH solution. When the titration reaches the
equivalence point, the chemist finds she has added 32.8 mL of NaOH solution.
Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.

You have chosen Methylamine as your weak base in the buffer solution. You have already added enough of the
conjugate acid salt to make the buffer solution concentration at 0.48 M in this salt. The desired pH of the buffer
should be equal to 9.75.
To prepare the buffer, a total volume of 550 mL is required. The stock solution of the weak base is available at 1
gallon with a concentration of 0.98 M. (Remember the lesson on dilution: C1V1=C2V2)
4. How many mL should be taken from the stock solution to prepare the desired buffer solution?
(round off final answer to 1 decimal place)
