|
|
|
solubility
|
the concentration of a saturated solution at a given temperature
|
|
|
saturated
|
a solution that holds as much solute as it is capable of holding stably at a given temperature
|
|
|
unsaturated
|
a solution that contains less solute than it could hold stably at a given temerature
|
|
|
why do solutes dissolve in sovents?
|
because the solution they form is more stable than a getergeneous mizture of the individual subsances.
