, Introduction:

Part 1

The purpose of this lab was to confirm the mass percent of a given hydrate. Also to

confirm the empirical formula with the known formula. An empirical formula is the simplest

ratio of the atoms in a molecule (Empirical Formula 2). The water lost was calculated to show

how accurate the procedure was to the known hydrate given.

Part 2

The purpose of this lab is to find the mass percent of water in an unknown hydrate. The

mol ratio was also used to determine the empirical formula of an unknown substance. A hydrate

is a salt that utilizes water in its structure. In the lab the hydrate was heated up to find the water

lost, the remaining residue was known as the anhydrous. Calculating the water lost and

comparing it to the knowns that were given will tell which hydrate was used. Percent error will

play a factor in how accurate the measurements are.


Procedure:

Part 1

We began by obtaining a crucible and massing it over an electronic scale. We then filled

the crucible with 1.175 grams of copper sulfate with a scoop, weighed it, subtracted the mass of

the empty crucible from it, and recorded the result. Afterwards, for the first cycle, the crucible

and its lid were placed on a heating plate at its highest temperature for 15 minutes. After the first

10 minute heating period, it was heated with the lid half off. Following that, the crucible was

then cooled for another 10 minutes and its mass documented. For cycle two, this process was

repeated. Afterwards, the crucible was then weighed, and its final mass was subtracted from its

original hydrated mass to determine the percent of its mass that is H2O. We simultaneously did
