Which instrument is used for dispensing liquids during titrations?

• A. Burette
• B. Graduated Cylinder
• C. Beakers and Flasks
• D. Meter

Answer: (A)

In a titration you need to add the titrant in precise, controllable amounts and know exactly how much has been added. The instrument that does this best is the burette. It’s a long, graduated glass tube with a stopcock at the bottom, which lets you release very small volumes and read the exact amount delivered, typically to the nearest 0.01 mL. This precise dispensing and measurement are essential to determine the endpoint and calculate the unknown concentration.

A graduated cylinder can measure volume but isn’t designed for the slow, controlled addition needed during a titration, and it lacks the fine control of a stopcock. Beakers and flasks are useful for holding and mixing solutions but don’t provide the precise delivery required. A meter isn’t the standard equipment for titration dispensing either.
