The substance that dissolves a solute is referred to as the solvent. ![]() The substance that gets dissolved is referred to as the solute. In the example of Kool-Aid, the sugar and mix are dissolved into water. In a solution, one or more substances are dissolved into another substance. Examples are sea water, Kool-Aid, antifreeze, seltzer water, and gasoline. Solution :: A special kind of mixture called a solution is where mixing occurs at the molecular level. If the atoms can only be separated with chemical reactions, they are complex molecules, not mixtures. Mixtures are combinations of compounds that can be separated by mechanical or physical processes. For example, mud, cake batter, milk, salad, latex paint, black top (asphalt and gravel). ![]() Mixture :: A mixture is simply a combination of two or more substances that do not react to form something new. ![]() Sadly, our “experiment” didn’t turn out as expected. STEM Club kids were delighted the day I told them we were making rock candy in class. Whenever I teach introductory chemistry, one of my favorite activities is to create rock candy. Rock candy is formed by allowing a supersaturated solution of sugar and water to crystallize onto a surface suitable for crystal nucleation, such as a string or stick. ![]()
