• You have heated a solid to dryness, but need to make sure all of the water evaporates, what piece of equipment do you need?

• When would using a bunsen burner be more appropriate than using a hot plate?

Transfer pipette or 5.00 graduate cylinder.

Watchglass or evaporating dish

• When would using a hot plate be more appropriate than using a bunsen burner.

• After you are finished with your lab, what safety measures do you need to take?

If open flame is not permitted, temperature <100C and when heating flammables

Disposal, clean off lab tables and wash your hands.
