During titrations, which device allows precise delivery of a titrant?

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

Answer: (C)

Delivering the titrant in precise, controllable amounts is essential in titrations to pinpoint the exact moment the reaction reaches its endpoint. The device that provides this level of control is the burette: a long, graduated glass tube with a stopcock that allows you to add the titrant drop by drop and read the volume delivered with high accuracy, often to 0.01 mL. This precision lets you calculate the exact amount of titrant needed to reach the endpoint. A graduated cylinder is used for rough volume measurements and isn’t designed for controlled, incremental delivery. A meter isn’t a tool for delivering titrant in a titration, and beakers or flasks are used for holding and mixing solutions rather than precisely delivering small volumes.
