Objectives:  Use stoichiometry to experimentally
determine the water of hydration in a crystal
Announcements: These labs will come in together
Rough draft is due on Monday.

Warm-up:  Show me your procedure||Goggles on!

Hydrates Lab (Part 2) -
Clean & mass a crucible & cover
Determine the formula for a hydrate:

MgSO₄ · XH₂O
Mass out 4-5 grams into your crucible
Record the mass and heat & mass again

Homework: Hydrates Lab (Part 1) -
Write purpose, procedure, data table and calculations (annotated) - rough draft
(Show me this part tomorrow)
