Title: Separation of a Mixture of Solids

Purpose: Learn and demonstrate how to separate different ingredients from a mixture of solids using different methods based on the properties of each ingredient.

Procedure: I weighed mixture and tools, and proceeded to begin separating each ingredient. I used a magnet to separate the iron from the mixture. Then I heated the mixture in water to get the non-soluble sand out. Then I filtered out the benzoic acid after cooling it into a crystal form. Lastly, I allowed the water to evaporate leaving behind only the salt. If any party was interested water does not evaporate fast enough for my liking. Data:

NET. MASS OF BENZOIC ACID CRYSTALS.5 GI HAVE A LITTLE LEFTOVER BENZOIC ACID AT THE BOTTOM OF THE CUP THAT I COULDN’T GET TO POUR OUT, AND A FEW CRYSTALS LEFT IN WATER AFTER FINISHED WITH THIS STEP THAT APPEARED LATER WHILE EVAPORATING.

Questions:

A. I thought it was rather obvious to use the magnet for the iron filings, but really did not have an educated guess for how to separate the rest.

B....
