| solvent | The part of the solution that is present in the largest amount and dissolves a solute |
| solution | a well-mixed mixture that has a solvent and at least one solute. |
| 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. |
| solute | A solution is a well-mixed mixture that has a solvent and at least one solute. |
| solubility | A measure of how much solute can dissolve in a solvent at a given temperature |
| dilute solution | A solution that has just a little solute dissolved in a certain amount |
| concentrated solution | A solution that has a lot of solute in a given amount of solvent |
| unsaturated solution | A solution that can still hold more solute |
| supersaturated solution | A mixture that has more dissolved solute than can be predicted by its solubility. |
| saturated solution | A solution in which the solvent cannot dissolve any more solute. |
| base | A substance that feels slippery, tastes bitter, and turns red litmus paper blue |
| corrosive | To eat away at other materials |
| acid | A substance that tastes sour, reacts with metals, and carbonates and turns blue litmus paper red |
| indicator | A compound that changes color when it comes in contact with an acid or base. |
| hydroxide ion (OH-) | A negative ion made of oxygen and hydrogen |
| neutralization | A reaction of an acid with a base, giving a solution that is not as acidic or basic as the starting solutions were |
| pH scale | A range of values from 0-14. It expresses the concentration of hydrogen ions in a solution. |
| salt | Any ionic compound that can be made from the neutralization of an acid with a base. It is made from the positive ion of the base and the negative ion of an acid. |
| hydrogen ion (H+) | An atom of hydrogen that has lost its electron |
| mechanical digestion | Physical process in which large pieces of food are torn and ground into smaller pieces. |
| digestion | Process which breaks down the complex molecules of foods into smaller molecules. |
| chemical digestion | Process by which large molecules of food are broken down into smaller molecules with the help of enzymes |
