CLEAN-UP
WARNING: Reserve the unused diluted NaOH solution in the Florence flask for the next experiment. Label with your Name and Section Number and store as directed.
Notes:
- Drain the burette and dispose of remaining NaOH from the burette in the designated Acid-Base Waste container.
- Your pipette should be rinsed well with tap water followed by distilled water.
-
Rinse the burette five times with ten mL portions of distilled water to remove all traces of NaOH from the burette and tip.
-
Leave the burette filled with distilled water and the funnel inverted on the top.
-
A 10 point deduction will be incurred if the instructor detects base in the burette.
-
Wipe your bench-top thoroughly with wet paper towels to remove any traces of acid or base.
-
Assure that no paper towels have been placed in the sinks.
