All of which increase the
collisions
, exposing undissolved particles to the solvent, and thereby increasing solvation for solid solutes.
1) The Solvation Process
Hydration:
solvation in water.
"Like dissolves like"
Bonding of particles.
Intermolecular forces among particles.
Polarity of particles.
Solvation:
the process of surrounding solute particles with solvent particles to form a solution.
Solute-Solvent Attraction

Solute-Solute Attraction
Types of Solutes
Molecular Compounds
Do not break down into atoms; rather, they break down into individual, unlinked molecules.
Examples
Polar-Polar
Sugar in Water
Nonpolar-Nonpolar
Oil in Benzene
Dipole-Dipole Attraction between solute and solvent

Molecular Attraction between solutes
Ionic Compounds
Broken down into ions.
Dipole-Ion Attraction

Ion-Ion Attraction
Examples
Soluble
NaCl
Insoluble
Gypsum (Strong Ion-Ion Attraction)
3) Types of Solutions
Saturated Solutions:
one that contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure.
Supersaturated Solutions:
one that contains more dissolved solute than a saturated solution at the same temperature.
Unsaturated Solutions:
one that contains less dissolved solute for a given temperature and pressure than a saturated solution.
4) Henry's Law
At a constant temperature, solubility is directly proportional to pressure.
