Chemistry Ch 13 Vocab

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
