Solubility: Factors affecting dissolving ability


Polarity


Polaritypolar dissolve in polar; non-polar in non-polar


Polaritypolar dissolve in polar; non-polar in non-polarTemperature


Polaritypolar dissolve in polar; non-polar in non-polarTemperatureSolids are more soluble in water as temperature increases


Polaritypolar dissolve in polar; non-polar in non-polarTemperatureSolids are more soluble in water as temperature increasesGases are less soluble in water as temperature increases


Polaritypolar dissolve in polar; non-polar in non-polarTemperatureSolids are more soluble in water as temperature increasesGases are less soluble in water as temperature increasesPressure


Polaritypolar dissolve in polar; non-polar in non-polarTemperatureSolids are more soluble in water as temperature increasesGases are less soluble in water as temperature increasesPressureSolids and liquids: solubilities aren't affected by pressure.

Solubility: How solutes dissolve


Solvation


SolvationIndividual atoms, ions, or molecules are surrounded by solvent molecules and brought into solution.


SolvationIndividual atoms, ions, or molecules are surrounded by solvent molecules and brought into solution.When water is the solvent, the process is called hydration.
