|
Solube |
Capable of being dissolved |
|
|
Solution |
Homogeneous mixture of 2 or more solutions in a single phase |
|
|
Alloys |
Solutions made of 2 or more solids (metals) |
|
|
Suspensions |
Mixture where particles are so big they fall to bottom unless constantly stirred |
|
|
Colloida |
Mixtures with medium particles that don't fall out of the solution |
|
|
Tyndall effect |
Light scattered by colloidal particles dispersed in a transparent medium (identifies mix. as solution or colloid) |
|
|
Concentration |
Measure of amount of solute in solvent |
|
|
Dikute |
Not concentrated, small amount of solute in solution |
|
|
Electrolytes |
Substance that dissolves in water to make electricity conducting solution (contains metal; ionic) |
|
|
Nonelectrolytes |
Substance that dissolves in water to make non conducting solution (no metal) |
|
|
Factors affecting rate of dissolution |
Crushing: increases surface area Stirring: causes fresh solvent to solute interaction Heating: speeds up solvent particles |
|
|
Solution equilibruum |
Point where things are dissolving/re-crystallizing at the same rate |
|
|
Saturated solution |
Contains maximum amount of dissolved solute |
|
|
Unsaturated somution |
Contains less solute than saturated solution under same conditions |
|
|
Saturation point |
Point where no more solute will dissolve in solution |
|
|
Supersaturated solution |
Contains more solute than saturated solution under same conditions |
|
|
Bydration |
Solution process with water as solvent (ions said to be hydrated or hydrates) |
|
|
Miscibke |
Liquids that dissolve in one another |
|
|
Immiscible |
Liquids that don't dissolve in one another |
|
|
Increase in pressure results in |
Increased gas solubility in liquids (no effect on liquid-liquid solubility) |
|
|
Increase in temp results in |
-Decrease of gas solubility in liquids -Increase of solid solubility in liquids |
|
|
Effervescence |
Rapid escape of gas from liquid it's dissolved in (opening soda bottle) |
|
|
Henry's Law |
Solubility of gas is directly proportional to partial pressure of the gas on liquid surface |
|
|
Molarity |
M= moles of solute/ L of solution |
|
|
Molality |
m= moles of solute/ kg of solvent (used for changes in temp) |
