| Question | Answer |
| solution | mixture of two or more substances; solute and solvent |
| saturated | solution that has dissolved all solute |
| unsaturated | solution that can still dissolve more solvent |
| supersaturated | a solution with more solute dissolved than the maximum amount on the chart |
| concentration | the amount of solute dissolved in an amount of solvent or solution |
| molarity | the number of moles per amount of solute (usually L) |
| colligative properties | properties that depend of the concentration of a solute |
| boiling point elevation | when the boiling point of a solvent is increased when another compound is added, so the solution has a higher boiling point than the pure solvent |
| freezing point depression | when adding a solute to a solvent decreases the freezing point of the solvent |
| solubility | the ability for a solute to dissolve in a solvent |
| solute | a substance dissolved in another substance |
| solvent | the substance in which the solute is dissolved |
| solution equillibrium | the state where both reactants and products are present in concentrations that won't change over time |
| equilibrium | the state where opposing forces or influences are balanced |
| equilibrium constant | the value of the reaction when it has reached equilibrium |
| equilibrium expression | the ratio of the concentrations of the products over the reactants |
| Le Chatlier's principle | can be used to predict the effect of a change in conditions on a chemical equilibrium |
| dilute | to make a liquid thinner or weaker by adding water or another solvent to it |
| concentrated | present in a high proportion relative to other substances |
| reversible reaction | a reaction where the reactants form products, which react together to give the reactants back |
| dissolving | become or cause to become incorporated into a liquid so as to form a solution |
| crystallization | when mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs |
| products | are species formed from chemical reactions |
| reactants | substances that start a chemical reaction |
