Term | Definition |
---|---|
Heterogeneous Mixture | >2 substances; >2 phases; Not uniform |
Homogeneous Mixture | AKA solution; 2+ substances in a single phase with uniform composition |
Solution | A homogeneous mix of 2+ substances in a single phase |
Solvent | Present in greater amount; Does the dissolving |
Solute | Present in lesser amount; What is being dissolved |
Suspension | When particles of a solid are too large to dissolve so they settle |
Colloid | When particles are too large to dissolve but too small to settle |
Tyndall Effect | Used to determine the difference between a colloid and a true solution |
Electrolyte | Dissolve in a solution to produce ions; support electric current; Ionically bonded |
Non electrolyte | Dissolve in a solution; will NOT produce electric current; Covalently bonded |
Dissolution | The rate at which a solid dissolves |
Solubility | A given volume of solvent can't dissolve more solute |
Saturated Solution | One that has dissolved the max amount of solute for the given T & V |
Unsaturated Solution | One that is still able to dissolve more solute for a given T & V |
Supersaturated Solution | One that has been forced to dissolve more than it should for a given T & V |
Dissociation | The separation of ions in a solution |
Nonpolar solvent | Dissolve fats, oils, and grease |
Miscible | 2 or more mutually soluble liquids |
Immiscible | 2 or more mutually INsoluble liquids |
Henry's Law | The solubility of a gas in a liq increases w/ increasing P and decreases w/ decreasing P |
Effervessence | The escape of a gas from a liquid in which it is dissolved (Pop) |
Exothermic | Released energy, feels hot |
Endothermic | Absorbed energy, feels cold |
Concentration | Refers to the amount of solute in a given quantity of solvent |
Dilute | make a liquid thinner or weaker by adding water or another solvent to it |
Molarity |
