| acid | a chemical that contributes hydrogen ions, H+, to a solution |
| alloys | solutions of two or more metals |
| atmospheres | the unit used to measure atmospheric pressure |
| base | a chemical that contributes hydroxyl ions, OH-, to aolution |
| colloids | a type of mixture in which the particles are between 1.0 and 1,000 nanometers in diameter |
| dissolved | the state in which solute particles are evenly distributed throughout a solvent |
| dissolving rate | the length of time it takes for a certain amount of solute to sissove in a solvent |
| electrolytes | chemicals that form ions and conduct current when dissolved in water |
| hydrated | combined with water or the elements of water |
| neutral | a solution that has a pH of 7, meaning it has equal numbers of H+ and OH- ions. |
| pH | the exact concentrations oh H+ ions and OH- ions in a solution |
| pH indicator | a solution or object that changes color to identify the pH of a solution |
| pH scale | a scale that runs from 0 (strongly acidic) to 14 (strongly basics) |
| saturated | the state of a mixtrue in which the maximum amount of solute has dissolved in a solution |
| solubility | refers to the amount of solute that can be dissoved in a certain volume of solvent under certain circumstances. |
| solubility value | a set of rules that identifies whether a combination of ions will dissolve or form a precipitate in water. |
| solutes | the substance in a solution in the smallest amount |
| solution | a mixture of two or more substances that is homogeneous at the molecular level |
| solvent | the component of a solution that dissoveds the solute and is present in the greatest amount |
| supersaturated | condition of a solution when more solute has dissolved than is normally possible at a given temperature |
| suspensions | a type of mixture in which the partlcles are larger than 1,000 nanometers in diameter. |
| system | a collection of matter and processes that occur in a certian space and can be studied |
| Tyndall effect | a way of visually distinguishing colloids from true solutions. |
| unsaturated | a solution in which it is possible for more solute to be dissolved. |
