1. Based on the principles of chemical equilibrium, how should the % dissociation vary as the concentration of HX is increased? Do your data agree with this conclusion? Cite specific data in your answer and possible reasons if the trend was not followed.
2. For each of the following, decide whether the calculated Ka is too high, too low, or not in error.
a) The buffer labeled pH 4.00 is 3.80.
b) Solution #3 was diluted to 45 mL instead of 50 mL.
3. The measured pH of solution #6 was determined to be 4.62. Calculate Ka using the volumes for this solution. Show all your work.
