One day we walk into the lab to discover that all of the labels have been peeled off of the chemical bottles. We have a list of the
chemicals that were in the lab and we have looked up each chemical’s physical properties. We have created a list of all the chemicals
and their properties. We then go into the lab and analyze each chemical. Use the table of physical properties that follows to determine
the identity of each chemical.

WORKSHEET G—EXTRA CREDIT
Jim’s teacher gave him samples of several mixtures. Jim’s assignment was to design methods to separate the substances of each
mixture by applying the concepts that he had learned in science class. Jim began by going to reference books and researching as
much as possible about the substances in the various mixtures. He then proposed a method of separation for each mixture. Using
science books, the internet or other reference material, find out as much as you can about the physical and chemical characteristics of
each of the substances in the given mixtures. Record the information in the table below.
Mixture Substances present Information about the substances
B Those found in pen ink
Now that you have researched the physical and chemical properties of the substances in the different mixtures, propose a separation
method for each mixture. Record the methods in the following chart.
Mixture Separation Method
A. Tin & Carbon
B. Pen Ink
C. Sulfur and Sodium Chloride
D. Sulfur, Sand and Iron Filings
E. Sulfur, Sodium Chloride & Sand
