Objectives: Experimentally determine
the formula for a hydrate
Announcements:
Dehydrate copper (II) sulfate but predict
dry mass during dehydration. Show me
your calculations
Announcements: Stoichiometry Rules!
Prelab: What will be the mass of anhydrous
Copper (II) Sulfate when dehydrated? Start
with between 1 and 2 grams. Weigh* it out
exactly. In a crucible heat strongly for 8 min.
with the lid on. Do your predictions, show it
to me. When, when cool, get the new mass*.
