Example Questions

Example Question #1 : Laboratory Equipment

Which choice of lab equipment is never used to make accurate volume measurements?

Possible Answers:

Graduated cylinder

Volumetric flask



Correct answer:



Graduated cylinders are often used for measuring volumetric quantities. As these have several markings, they are considered accurate. Volumetric flasks are also used to accurately measure liquid volume quantities. Lastly, burettes are used to accurately measure volumes of liquid during titrations.

In contrast, beakers are not typically used to measure accurate quantities of liquid; though they have markings on them, these are approximate measurements. Graduated cylinders are often used to accurately measure out a liquid, and beakers to then hold the liquid.
