| Term | Definition |
|---|---|
| Solute | a substance whose particles are dissolved in a solution |
| Solvent | the substance in which the solute dissolves |
| Dissociation | the process in which an ionic compound separates into ions as it dissolves |
| Dispersion | breqking into small pieces that spread throughout the water |
| Ionization | the process in which neutral molecules gain or lose electrons |
| Solubility | the maximum amount of a solute that dissolves in a given amount of solvent at a constant temperature |
| Saturated solution | one that contains as much solute as the solvent can hold at a given temperature |
| Unsaturated | a solution that has less than the maximum amount of solute that can be dissolved |
| A supersaturated solution | one that contains more solute than it can normally hold at a given temperature |
| Concentration | of a solution is the amount of solute dissolved in a specified amount of solution |
| Molarity | is the number of moles of a solute dissolved per liter of solution |
| Acid | a compound that produces hydronium ions when dissolved in water |
| Indicator | any substance that changes color in the presence of an acid or base |
| Base | a compound that produces hydroxide ions when dissolved in water |
| Neutralization | the reaction between and acid and a base |
| Salt | the negative ions in an acid combine with the positive ios in a base to produce this ionic compound |
| pH | of a solution is a measure of its hydronium ion concentration |
| Buffer | a solution that is resistant to large changes in pH |
| Electrolyte | a substance that ionizes or dissociates into ions when it dissolves in water |
