PERFORMING THIS EXPERIMENT
2.
Fill one burette with acid and the other with base. Each student will perform two titrations during this

Clean two burettes; your instructor will describe how.

lab.
Drain 25.0 mL of either acid or base (depending on which acid/base you have been assigned) from your
burette into an Erlenmeyer flask. (If “A is to be titrated with B" then A goes in first, and B will be added
to A.)
Read and record the pH in your flask.
Add 5.0 mL of the second reagent (acid or base) to your flask, from the other buret. Read and record the
new pH.
Continue adding this second reagent in 5.0 mL increments until either a total of 20.0 mL has been added
or the pH changes by 3 units from the previous reading. Add ten 1.0 mL portions and then resume 5.0
mL increments until a total of 50.0 mL has been added. After each of these additions the flask should be
swirled to insure mixing and the pH should be measured and recorded in table A.
Rinse your flasks with tap water followed by deionized water. Drain well.
Clean your burettes as described by the instructor.
Refill your burettes with the second acid base set.
10. Repeat steps (3) through (6) for this second titration. Record the pH's in table B.
11. Clean your flasks and burettes.
