Solutions

Vocabularysolvent: substance that dissolves other materials solute: substance that is disolveddilute: describes a solution with a small amount of solute compared to the amount of solventconcentrated: describes a solution with a large amount of solute compared to the amount of solvent

Notes*When a substance dissolves, it breaks down into individual particles.*In a solution, the particles are evenly distributed.*In sugar water, water is the solvent and sugar is the solute.*Many common solutions are solid solutes dissolved in liquid solvents.*Solutions can also be made using liquids as both the solvent and the solute. For example: food coloring in water.*Solvents can remove oils from flowers, peppermint, cloves, and vanilla beans. *The solvent or solute in a solution can be a solid, a liquid or a gas.*Air is a gas dissolved in a gas.*Gasoline is a liquid dissolved in a liquid.*A nickel coin is a solid dissolved in a solid.*Tooth fillings are a liquid dissolved in a solid.*Soda pop is a gas dissolved in a liquid.*Solutions can has a little or a lot of solute to make them concentrated or diluted. *Stirring a solution makes the particles of both the solvent and the solute move around more so dissolving happens faster.*The smaller you make the solvent pieces the faster they will dissolve. *Heating a substance will make its particles move faster and bounce around more causing them to dissolve faster.

Phillipus Paracelsus thought that there was a substance from which all substances came. He believed if he found it, it would dissolve anything.

Three Ways to Dissolve Faster1. Stir2. Increase the surface area by making pieces smaller3. Heat

2 solids = a nickel

Gas dissolved in Liquid = Soda Pop

gasoline = a liquid dissolved in a liquid

food coloring in water = liquid dissolved in a liquid

sugar water = solid dissolved in a liquid

air = gas dissolved in a gas

fillings = liquid dissolved in a solid

steam = liquid dissolved in a gas

tea + solid dissolved in a liquid
