Final answer:
To make accurate solutions in an experiment, A) Volumetric glassware is used, which includes tools like volumetric flasks, pipettes, and burets that are designed to measure exact volumes of liquids.
Step-by-step explanation:
In the experiment described, the type of glassware used to make accurate solutions is A) Volumetric glassware. Volumetric glassware is specifically designed to measure precise volumes of liquids and includes instruments such as the volumetric flask, pipette, and buret. Each of these tools has distinct applications. For example, a pipette is used to deliver a specific volume quickly and accurately, while a volumetric flask is designed to contain a single, precise volume when filled to the calibration mark. On the other hand, burets are often used in titrations to dispense exact volumes of a liquid.
A graduated cylinder can also be used for measuring liquid volumes but is generally less precise than volumetric glassware. Beakers and test tubes are not used for accurate measurements due to their lack of precision.
