Final answer:
Calipers can measure tablet thickness (True), while friabilators determine tablet friability, not disintegration or dissolution rates (False).
Step-by-step explanation:
The answers to the student's questions are as follows:
1. A caliper or hand gauge may be used to measure tablet thickness. A. True
2. A friabilator is used to determine the disintegration and dissolution rates of a tablet. B. False
The friabilator is specifically designed to measure the friability of a tablet, which relates to the tablet's ability to resist abrasion or breakdown upon handling. The dissolution rate of a tablet, on the other hand, is measured using dissolution test apparatus, not a friabilator. The dissolution test evaluates the amount of time it takes for the active drug substance to dissolve in the fluids in which it is immersed.
