Solvated
solute particles surrounded by solvent
Exotthermic
Release Heat
Negative Heat of solution
Endothermic
absorbing hear
Positive Heat of Solution
Temp-if solute is a solid
increase temp=increase solubility
ex:Kool Aid in H2o
Temp If solute is a gas....
increase temp=decrease solubility
ex: soda
Henry's Law
increase pressure = increase soluability
Increase ____________ = increase amount of _______________ dissolved
pressure, gas
ex soda
Factors affectiong solubility
Type of Solute/Solvent
Pressure
Temperature
miscible
are soluable in each other
vinegar and water
Immiscible
not soluable in each other
ex: water & oil
Steps for making supersaturated solution
heat saturated solution
add more solute
cool slowly
Supersaturated Solution
has more solute than a saturated solution at same conditions
More will cause crystiliziation
Saturated Solution
Contains max amount of solute
More will not dissolve
Unsaturated Solution
contains less than mazimum amount of solute
add more h2o it will dissolve
solution equilibrium
opposing rates of dissolving and crystallizing are =
