1. Solutions

2. A solution is a homogenous mixture of two or more substances.

3. Components There are two components to a solution. – The solute is the substance there is less of that gets dissolved – The solvent is the substance there is more of that dissolves the solute

4. Water and Soap Water is a great solvent because it is polar and abundant. Soap has a polar end and a nonpolar end, so it can dissolve oil but be dissolved by water.

5. Solubility Some substances are more soluble, meaning they dissolve easier. For solids, solubility increases when temperature increases. For gases, solubility decreases when temperature increases.

6. Concentration The more solute there is, the more concentrated the solution is.

7. Saturation There are 3 categories of concentration. – Unsaturated – a solution in which you could dissolve more solute Like semi-sweet tea to which you could add more sugar – Saturated – a solution in which you could not dissolve any more solute Like Chicken Express tea to which you could not add more sugar – Supersaturated – a solution in which more solute is dissolved than is normally possible at that temperature (unstable) This is how rock candy is created!
