Write a conclusion of 250 words discussing an experiment of you will be given a mixture containing various substances. Your goal is to use the physical properties of the substances to separate the mixture into its various components and the results. Make sure to answer the following questions in your conclusion. What did you do in this experiment? (List the procedural steps.) Which parts of the separation process were the most time consuming? Why might this be important on an industrial scale? Are there parts of the procedure that you would change if you could repeat this experiment? If so, what are they? Give at least one example from industry where a mixture must be separated in order to obtain the materials that are useful to society.

Explanation:

One substance alone cannot be a mixture. A mixture is made up of two or more different substances.

A mixture can contain solids, liquids and/or gases. The components in a mixture are not chemically joined; they are just mixed. That means we do not need to use chemical reactions to separate them. Mixtures can be separated using physical methods alone and that is what this chapter is all about: how to separate mixtures.
