Soluble
Compounds that can be dissolved in water
Insoluble
Compounds that will not dissolve in water
Solution
A homogenous mixture
Solvent
Larger component of a solution, usually water
Solute
Smaller component of a solution
Electrolyte
Ions separate in solutions to produce an electric current
Non electrolyte
Ions do not separate in solution
Saturated solution
Contains max amount of solute that can be dissolved
Unsaturated solution
Less solute that can be dissolved
Solubility
The max amount of solute that dissolves in a specific amount of solvent. It can also be expressed as grams of solute in 100 grams of solvent, usually in water
Hydration
Water molecules form around ions in solution
Dilution
Solution where water is added to increase the volume
Concentration
amount of solute dissolved in a specific amount of solution
Molarity
"M" moles of solute per liter of solution aka mol solute/L solution
Molality
"m" moles of solute per kilogram of solvent aka mol solute/Kg solvent
Mass percent definition
Concentration is percent by mass of solute in a solution. G of solute/100 g of solvent x 100
Mass percent formula
G of solute/100 g of solvent x 100 OR Mass of solute/Mass of solute+Mass of solvent x 100
Volume percent definition
% volume of solute (liquid) to volume (mL) of solution
Volume percent formula
mL solute/mL solution x 100 OR mL solute/100 mL of solution x 100
Molal freezing point constant
Kfreezing aka Kf
Molal boiling point constant
Kboiling aka Kb
Freezing point depression
∆ Tfreezing= Kfm
Boiling point elevation
∆ Tboiling = Kbm
pH
-log[OH-]
