Question

Heating a hydrate to constant mass in a crucible is a common lab procedure. Typically, this procedure is carried out in order to determine the number of waters associated with a salt. While performing this procedure, care must be taken, however, to ensure the integrity of the sample. Match the common error with its result below.

Error 1: ????

Result 1: The compound will splatter causing potential loss of anhydrous product.
