You will get to learn about mixtures and solutions. Discover how to identify substances by their solubility, and explore techniques to separate mixtures.
After completing this tutorial, you will be able to complete the following:
What is a mixture?
~ A mixture is a substance in which two or more different materials are mixed together, but not chemically combined or changed.
What happens to the physical properties of sand and water when these two substances are combined in a mixture?
~ When sand and water are combined in a mixture, both substances maintain the same physical properties.
What happens to the physical properties of salt and water when the two are combined in a mixture?
~ When salt and water are combined in a mixture, the physical properties of both are changed. When mixed, the salt appears to disappear because it dissolves, forming ions surrounded by water molecules.
What is dissolution?
~ Dissolution is the process by which one substance dissolves into another substance in a mixture.
