Experiment 2
Identifying a Mixture: How can determining basic properties of a substance allow you to identify the substances in a mixture?
Purpose/Hypothesis
Because the components in a mixture keep their own chemical properties, scientists can identify the substances in a mixture by knowing the properties of its components. In order to identify a substance, its components are isolated and tested.
In this experiment, you will determine different properties of several substances that are similar in appearance. You will then have a partner create a mixture with two of the substances. Using the properties of the substances that you determined, you will identify the composition of the mixture.
The substances you will use are three household items: flour, sugar, and baking soda. The properties you...
