1) What two experimental methodologies will you use to determine the Ka of the unknown weak acid in this
experiment? (Check lab procedure)
2) After completing the acid-base titration in Part I, how will you determine the accurate volume of titrant (0.1 N
Standard Sodium hydroxide solution) at equivalence point from the pH curve?
3) When calibrating the Drop Counter, what is the suggested drop rate from the burette (drops per second) in
the procedure?
