Creating an Original Chemistry Procedure

Overview

I have attached the assignment instructions and the lab book reference for the original experiment.

Research problem: Separate a mixture of I2(s), potassium bromide(s), iron powder, and aluminum oxide powder, and determine the percent by mass of each component of the mixture.

This should involve only physical (not chemical) processes.

It is not practical to using melting to separate any of the above solids.

Give careful thought in designing the procedure so that the mass of each

component will be obtained with the highest degree of accuracy possible.

Tell the student each time he or she needs to weigh the sample so the percent of each component can be determined. What is needed in the experiment: Objective paragraph, materials list (including exact chemical names), procedures. The procedure steps need to be full sentences with proper physical separation techniques to achieve the percent by mass and separate each component. The actual compound names are needed.
