A procedure that cannot be performed on a hot plate but on a Bunsen burner is d. Heating a crucible to remove water from a hydrate.

Crucibles need to be heated up to ensure accurate measurements as water could easily get absorbed and trapped in the material in the crucible.

When heating the crucible, it is not recommended to use a hot plate as it might break. It is best to use a Bunsen burner which would allow the crucible to be held as it is heated.

The other options are wrong because:

a solvent can be heated on a hot plate to help a solute dissolvean isolated solid can be heated on a hot plate to dry it water is regularly heated on hot plates

In conclusion, heating a crucible on a hot plate is not recommended.
