Which glassware is most appropriate for heating liquids and simple mixing?

• A. Erlenmeyer flask
• B. Beaker
• C. Graduated cylinder
• D. Volumetric flask

Answer: (B)

Heating liquids and doing simple mixing call for a container that is easy to handle, tolerates heat well, and allows straightforward stirring and pouring. A beaker fits this role perfectly: it has a flat bottom for stable heating on a hot plate or over a flame, a wide mouth that makes it simple to add reagents and stir with a glass rod, and a convenient pouring spout to transfer liquids with minimal spilling. The volume markings are only approximate, but that’s fine for heating and mixing tasks where exact measurements aren’t required.

By contrast, an Erlenmeyer flask is shaped to reduce splashing during swirling, but its narrow neck makes stirring and pouring less convenient when you’re heating. A graduated cylinder is designed for precise volume measurements, not for heating or mixing. A volumetric flask is intended for preparing solutions to a exact volume and isn’t suited to heating or mixing.
