Baking soda will dissolve in water, but not in oil…..why?
“ Like dissolves like” refers to the bonding and polarity of the particles in the solute and solvent
Polar means a substance
has a positive and a
Ionic compounds in solution Cl - Na + Cl - Na + Na + Cl - Cl -
Only a certain amount of solute can dissolve in a solvent under a certain set of conditions
When too much solute is added to a solution at that temperature, the excess solute will crystallize
and fall out of solution
Solubility is the maximum
amount of a solute that
dissolves in a solvent at
a given temperature
A saturated solution
contains the maximum amount of dissolved solute
for a given amount of solvent
at a specific temperature and pressure
A supersaturated solution
contains more dissolved solute than a saturated solution
at the same temperature.
