Mixtures, Solutions, Solubility, Chemical Reactions
| Term | Definition |
|---|---|
| mixture | two or more substances sharing the same space that can be separated by physical means |
| heterogeneous mixture | a mixture in which you can identify all the parts |
| homogeneous mixture | a mixture that looks the same throughout and you cannot identify the parts |
| solution | a homogeneous mixture in which the parts are completely dissolved and is clear |
| suspension | a heterogeneous mixture in which the parts are heavy enough that they eventually settle to the bottom |
| colloid | a homogeneous mixture that has particles large enough to scatter the light, therefore you cannot see through it. |
| solubility | the ability to dissolve |
| solute | the substance that is being dissolved |
| solvent | the substance that is doing the dissolving |
| unsaturated | a liquid solution that can still hold more solute |
| saturated | a solution that cannot hold anymore solute; it is full |
| supersatured | a solution that is holding more solute than it should be able to |
| concentrated | a solution that is holding a lot of solute, or have very little solvent |
| dilute | a solution that is not holding very much solute, or has a lot of solvent. |
| soluble | able to dissolve |
| insoluble | not able to dissolve |
| Pure Substance | A substance that is not mixed with anything else |
| Physical Change | A change that does not alter the identity of a substance |
| Chemical Change | A change that produces a new substance after the reaction. |
| Distillation | A method to separate liquids based upon different boiling points |
| Evaporation | A simple method used to separate solid solutes from liquid solvents |
| Filtration | A method to separate undissolved solids from liquids |
| pH | a way of measuring how acidic or basic a solution is |
| Acidic pH | a pH of less than 7 |
| Basic pH | a pH of more than 7 |
| Neutral pH | a pH of exactly 7 |
| Law of Conservation of Mass | Matter cannot be created or destroyed, it can only change forms |
| reactants | the substances that mix to form a reaction |
| products | the new substance that is produced after a chemical reaction |
