◉ How should you prepare a buret for titration before loading it
with titrant? Answer: Condition the buret with titrant solution.
◉ Put the #'s in correct order:
When filling a buret for a titration, first adjust the buret in the clamp
so that ________. Then, _________ to add the titrant into the buret. The
titrant should be filled __________.
