Two clear solutions are combined to form a homogeneous mixture. As a solid chemical is added, the two seemingly inseparable solutions begin to "sort" into two layers. As more solid is added, the two layers become more distinct. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.
Concepts: Solubility, bonding, polar and nonpolar solvents.
Time Required: 15 minutes
Chemicals Provided: Ethyl alcohol and potassium carbonate.
