Solution |
A homogenous mixture that consists of one or more splurges uniformly dispersed at the molecular or ionic level throughout a medium known as the solvent |
|
|
Liquids |
Solutions do not have to be liquids |
|
|
Solute |
Material being dissolved (minority component by weight or concentration) |
|
|
Solvent |
Material doing the dissolving (majority component by weight or concentration) |
|
|
Molar concentration |
Moles per liter of solution |
|
|
Molal concentration |
Moles per kilogram of solvent (not kilograms of solution) |

Normality |
Equivalent per liter (term largely abandoned in both Chem and medicine) |
|
|

Amount of solute in 1 million parts of solution |
|
|
Miscible |
Liquids that are soluble in each other in all proportions (ex: water + ethyl alcohol) |
|
|
Immiscible |
Liquids that are poorly soluble in each other (ex: water + oil) |
|
|
Immiscible |
Liquids that are poorly soluble in each other (ex: water + oil) |
|
|
Colloids |
Not true solutions; one phase uniformly dispersed in a second phase , but none actually dissolved |
|
|
Solubility |
Amount of the solute that will dissolve in a given amount of solvent at a given temperature |
|
|
Saturated solution |
Contains the maximum amount of a solute |
|
|
Saturated solution |
Contains the maximum amount of a solute |
|
|
Supersaturated solutions |
Can exist, but are unstable and excess solute will come out of the solution and recrystallize |

|
Polar substances |
More soluble in polar solvents |
|
|
Non-polar substances |
Are more soluble in non-polar solventa |
|
|
Enthalpy |
Change that accompanies dissolving exactly one mole of solute in a solvent; heat of solution or energy change |
|
|
Endothermic enthalpy |
Components of the ionic substance must be separated, requiring energy |
|
|
Endothermic enthalpy |
Components of the ionic substance must be separated, requiring energy |
|
|
Exothermic enthalpy |
Ions are attracted to the dipoles of the water molecule, lowering the energy state |
