Solution
A homogenous mixture
Solute
Portion of solution in lesser quantity
Solvent
Portion of solution in greater quantity
Soluble
Maximum [] is greater then or equal to 0.1M 25 degrees
Low solubility
Max concentration is less then 0.1M @ 25 degrees
Solubility
The maximum amount of solute that can go into a given volume of solvent at a specific temp
Saturated solution
- At solubility
- Solid present
- Rates are equal (rate of ionization = rate of crystallization)
Iconic solutions
Formed by compounds that will dissociate into ions (to some degree) -ionic compounds ~metal - nonmetal (any anion) ~ammonium-nonmetal ~acids
Molecular solutions
No ions
Ex. C6H12O6 sā> C6H12O6 am
Ksp
Solubility product constant or ion product constant
Describes a saturated solution equilibrium
Describes the max []s of ions that can be in solution together
Predicting if a precipitate will form
Trail ksp < ksp ~> no ppt - below solubility
Trail ksp = ksp ~> no ppt-@ solubility
Trail ksp > ksp. ~> ppt - saturated solution
