Unformatted text preview: 1. Using the solutes and solvents at your disposal, create a snow globe. Discussion: 1. What is a saturated solution? 2. What does the phrase Like dissolves like mean? 3. What is the best solute/solvent combination? 1. Saturation is the point at which a solution of a substance can dissolve no more of that substance and additional amounts of that substance will appear as a precipitate. 2. The phrase like dissolves like means substance with the same physical chemistry, such as polarity, dissolves in one another. An example of like dissolves like is water and oil. Water is polar and oil is nonpolar, therefore they do not mix. 3. The best solute/solvent combinations are any nonpolar solvent (such as mineral oil or vegetable oil) and polar solutes (such as Epsom salt or sodium chloride). Source: Haugh, Thomas. 2001.
