Heather is doing an acid-base reaction. She has 25.00 mL of hydrochloric acid of unknown concentration in a flask. She wants to add a basic solution to the acid drop by drop, until all the acid has reacted.

Which tool would be best for adding the basic solution dropwise and for most precisely measuring the volume of solution added?
a graduated cylinder
an eye dropper
a beaker
a buret

A buret.

Reason: a buret is made for titrations — it lets you add liquid dropwise with a stopcock and gives very precise, graduated volume readings. The other options are not suited for precise, controlled addition or accurate volume measurement.
