Question

All titrant volumes (in mL) recorded from a labquest data table should be recorded to _____ decimal places.

a. 1
b. 2
c. 3
d. 4

Answer 1

Volumes from a titration experiment should be recorded to two decimal places, as typical burets measure to the nearest 0.01 mL, aligning with correct significant figures practice.

Step-by-step explanation:

The question is asking about the proper number of decimal places to use when recording titrant volumes from a lab experiment. According to LibreTexts, a typical buret permits volume measurements to the nearest 0.01 mL. In the context of significant figures, the least certain measurement dictates the number of decimal places that should be used. Given that a typical buret allows for measurements to be accurate to the 0.01 mL mark, it is reasonable to record volumes to two decimal places. This is in line with good laboratory practice, ensuring that all measurements are as precise as the equipment allows.
