Mass measurements of the crucible, lid, and sample are, Ask an Expert

Academics

The gravimetric analysis of this experiment is meant to be quantitative; therefore, all precautions should be made to minimize errors in the analysis.

a) The crucible and the lid are handled exclusively with crucible tongs in the experiment. How does this technique maintain the integrity of the analysis?

b) Mass measurements of the crucible, lid, and sample are performed only at room temperature. Why is the technique necessary for a gravimetric analysis?

c) Why is the position of the crucible lid critical to the dehydration of the salt during the heating process?
