| 317384482 | Solution | a well-mixed mixture that contains a solvent and at least one solute. | |
| 317384483 | Solvent | the part of a solution present in the largest amount. | |
| 317384484 | Water | "universal solvent". | |
| 317384485 | Colloid | is a mixture containing small, undissolved particles that do not settle out. | |
| 317384486 | Solute | what gets dissolved by the solvent | |
| 317384487 | Suspension | is a mixture in which particles can be seen and easily separated by settling or filtration. | |
| 317384488 | dilute solution | a mixture that has only a little solute dissolved in a certain amount of solvent. | |
| 317384489 | concentrated solution | a solution that has a lot of solute dissolved in the same amount of solvent. | |
| 317384490 | solubility | is a measure of how much solute can dissolve in a solvent at a given temperature. | |
| 317384491 | unsaturated solution | if you can continue to add more solute to the solution | |
| 317384492 | supersaturated solution | has more dissolved solute than is predicted by its solubility at the given temperature. | |
| 317758422 | Acid | a substance that tastes sour, reacts with metals and carbonates, and turns blue litmus paper red | |
| 317758423 | corrosive | they eat away at other materials | |
| 317758424 | indicator | compound that changes color when in contact with an acid or a base | |
| 317758425 | base | substance that tastes bitter, feels slippery, and turns red litmus paper blue | |
| 317758426 | hydrogen ion (H+) | an atom of hydrogen that has lost its electron | |
| 317758427 | hydroxide ion (OH-) | the negative ion made of oxygen and hydrogen | |
| 317758428 | pH scale | range of values from 0-14. | |
| 317758429 | neutralization | reaction between an acid and a base | |
| 317758430 | salt | any ionic compound that can be made from the neutralization of an acid with a base | |
