concentration
The ability of a substance to dissolve in a solvent.
solution
solute
concentration
solubility
Describes how much solute has been dissolved in a solution and is expressed in terms of molarity.
conductivity
concentration
solute
solubility curve
A solution in which the maximum amount of solute has been dissolved in a solvent.
saturated
supersaturated
unsaturated
agitation
A solution in which more solute can be added and dissolved. It is below the maximum amount of solute.
saturated
neutral
unsaturated
supersaturated
A solution that contains more of the dissolved solute than could be dissolved by the solvent under normal conditions. Increasing temperature or pressure can increase the maximum possible solute dissolved in a solvent.
saturated
supersaturated
unsaturated
concentration
A graph that compares the amount of solute that will dissolved in a given amount of solvent at various temperatures.
solubility curve
surface area
pH scale
direct variation
A factor that affects solubility by moving the molecules of the solute and solvent around to cause more collisions to increase the rate of solubility. Ex: stirring.
indicator
agitation
temperature
surface area
