What type of glassware would you use to mix small quantities of liquids?

Using a test tube is ideal for mixing small quantities of liquids due to its design and function. Test tubes are typically narrow and cylindrical, which allows for easy handling and mixing of small volumes without the risk of spillages. They are often used in laboratory settings for experiments that require smaller amounts of reactants or solutions.

Moreover, test tubes can be easily sealed with stoppers or caps, enabling the containment of reactions or the storage of samples. Their size makes them more suited than larger glassware options for procedures that involve careful mixing or observation of chemical reactions in smaller scales.

In contrast, flasks, beakers, and graduated cylinders are generally intended for larger volumes or specific applications that do not center around intimate mixing of small quantities. Flasks have wider mouths and are better for boiling or storing solutions; beakers are designed for easy pouring and holding of larger volumes; while graduated cylinders are used primarily for measurement rather than mixing.
