| solute | a substance dissolved in a solvent to form a solution |
| solvent | the dissolving medium in a solution |
| dissolving process | a solute and solvent undergo an electrostatic attraction which causes the ions to separate & results in a homogeneous solution |
| heterogeneous mixture | a mixture that has different properties in different regions of the mixture |
| homogeneous mixture | a mixture that is the same throughout |
| saturated solution | a solution that contains the maximum amount of solvent that will dissolve in a given amount of solute at a given temperature |
| unsaturated solution | a solution that can dissolve more solute |
| supersaturated solution | a solution that has been "tricked" to dissolve more solute that it normally should |
| molarity | moles of solute per volume of solution in liters |
| solubility | the amount of a substance that dissolved in a given volume of solvent or solution at a given temperature |
| percent concentration | the percentage of grams of solute per grams of solution |
| parts per million (PPM) | a method of measurement for the substance that is dissolved |
| hydronium ion | the H3O+ ion - a hydrated proton |
| hydroxide ion | the anion OH- |
| acid | Arrhenius - a substance that produces hydrogen ions in aqueous solution |
| acid | Bronsted-Lowry - proton donor |
| base | Arrhenius - a substance that produces hydroxide ions |
| base | Bronsted-Lowry - proton acceptor |
| dissociate | the decompostion of a complex substance into simpler constituents |
| buffer | a solution that resists changes in pH when limited amounts of acid or base are added |
| pH | the negative logarithm of the hydrogen ion concentration of a solution |
