| solution | A mixture containing a solvent and at least one solute that has the same properties throughout; a mixture in which one substance is dissolved in another. |
| solvent | The part of a solution that is usually present in the largest amount and dissolves a solute. |
| solute | The part of a solution that is dissolved by a solvent. |
| colloid | A mixture containing small,undissolved particles that do not settle out. |
| suspension | A mixture in which particles can be seen and easily separated by settling or filtration. |
| dilute solution | 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 much solute can dissolve in a given solvent at a given temperature. |
| saturated solution | A mixture that contains as much as dissolved solute as is possible at a given temperature. |
| acid | A substance that tastes sour, reacts with metals and carbonates, and turns blue litmus red. |
| corrosive | The way in which acids react with some metals so as to wear away the metal. |

| hydroxide ion (OH-) | A negatively charged ion made of oxygen and hydrogen. |
| pH scale | A range of values used to indicate how acidic or basic a substance is; expressed the concentration of hydrogen ions in a solution. |
