| suspension | A mixture in which particles can be seen and easily separated by settling or filtration. |
| solution | A very well-mixed mixture, having the same properties throughout. |
| solvent | The part of a solution that is present in the largest amount and dissolves a solute. |
| solute | The part of a solution present in a lesser amount and dissolved by the solvent. |
| colloid | A mixture with small undissolved particles that do not settle out. |
| dilute concentration | A mixture that has only a little solute dissolved in it. |
| concentrated solution | A mixture that has a lot of solute dissolved in it. |
| solubility | A measure of how well a solute can dissolve in a solvent at a given temperature. |
| saturated concentration | A mixture that contains as much solute in it as possible at a given temperature. |
| unsaturated concentration | A mixture in which more of the same solute can be dissolved. |
| supersaturated concentration | A mixture that has more dissolved solute than is predicted by its solubility at the given temperature |
| acid | A substance that tastes sour, reacts with metals and carbonates, and turns blue litmus red. |
| indicator | A compound that changes color when in contact with an acid or a base. |
| base | A substance that tastes bitter, feels slippery, and turns red litmus blue. |
| hydrogen ion (H+) | A positively charged ion (H+) formed of a hydrogen atom that has lost its electron. |
| hydroxide ion (OH-) | A negatively charged ion (OH−) made of oxygen and hydrogen. |
| pH scale | A range of values from 0 to 14 that expresses the concentration of hydrogen ions in a solution. |
| acid rain | Rainwater that is more acidic than normal rainwater. |
| neutralization | A reaction between an acid and a base. |
| salt | An ionic compound that can form from the neutralization of an acid with a base. |
