A
To calibrate the burette before use
B
To record the final results of the titration

Verified step by step guidance1
Understand the purpose of a prelaboratory assignment: It is designed to prepare students for the experiment by ensuring they grasp the theoretical concepts, calculations, and procedures involved in the experiment.
Recognize that volumetric analysis involves precise measurements, such as titration, which require familiarity with equipment like burettes and pipettes, as well as the chemical reactions involved.
A prelaboratory assignment typically includes questions or tasks that reinforce key concepts, such as stoichiometry, molarity calculations, and the proper use of laboratory equipment.
The assignment may also include safety guidelines and procedural steps to ensure students can perform the experiment accurately and safely.
The primary purpose of the prelaboratory assignment is not to calibrate equipment, record results, or clean glassware, but rather to ensure students are theoretically prepared to conduct the experiment effectively and understand its scientific basis.
