AHeating the sample to drive off water
BWeighing a dried precipitate accurately
CDelivering measured volumes of liquid
DStoring the sample away from the air
Answer & Solution
Correct answer: C. Delivering measured volumes of liquid
1. A buret is a graduated tube fitted with a tap.
2. It delivers variable liquid volumes precisely, reading to the nearest 0.01 mL.
3. This lets titrant be added a little at a time until the reaction is just complete.
4. Heating and weighing belong to gravimetric methods, not to the buret.
