1. Suppose 100.0 mL of an aqueous solution containing an unknown monoprotic acid (called HA) is titrated with 0.150 M KOH. The titration requires 47.82 mL of the potassium hydroxide to reach the equivalence point. What is the molar concentration of the unknown acid solution?

2. You are asked to make a buffer of pH 4.90 for control of a chemical reaction. Using the table of pKas in the experimental procedure (Part 4), select an appropriate acid/base pair and clearly state the pair that you selected. Calculate the volume of the acid solution and the volume of the conjugate base solution that would be needed to make a buffer with a total volume of 150. mL. Assume all stock solutions are 1.00 M. Show all of your work.

3. Using the buffer solution prepared above in Question 3, what would be the resulting pH of the buffer after the addition of 15.0 mL of 0.550 M HCl?
