Solution
|
When substances particles meet liquid particles they can mix together to form a special mixture called a solution. This process is called dissolving.
|
|
|
Dissolve
|
When a substance goes into solution. The process of making a solution
|
|
|
Solute
|
The substance being dissolved.Solute is the solid, liquid, or gas that dissolves
|
|
|
Solvent
|
The liquid that the solute dissolves in. Could be a solid or gas.
|
|
|
Insoluble
|
When a substance will not dissolve
|
|
|
Concentration
|
The amount of substance dissolved in a liquid. Compare the amount of solute in a given amount of solvent expressed in g/100mL
|
|
|
Concentrated
|
More solute
|
|
|
Dilute
|
Less solute
|
|
|
Saturation
|
When the maximum amount of solute is dissolved in a solution. When the solution hits its solubility point and cant hold any more solute it is saturated. Once you get past this point there will be a precipitate.
|
|
|
Unsaturated solution
|
Solvent can still dissolve more solute. If you add more solute it may dissolve. Unsaturated is when the solvent is still capable of dissolving more solute.
|
|
|
Saturation Point
|
Is the maximum amount of solute that can be dissolved in a given amount of solvent at a particular temperature. This is unique for each substance
|
|
|
Precipitate
|
When a solute comes out of solution. "Rains Out" of a saturated solution if excess solute is added. The solute that will not dissolve in the solution.
|
|
|
Solubility
|
The maximum amount of solute that can dissolve in a solvent at a given temperature and pressure. It is a characteristic property of both the substance and the liquid.
|
|
|
Homogeneous solution
|
Is a uniform solution, the same throughout
|
|
|
Heterogeneous solution
|
Is a non-uniform solution, not the same throughout
|
|
|
Suspensions
|
Materials do not dissolve, but are light enough to stay suspended within the liquid
|
|
|
Colloids
|
Behave like solution and suspensions
|
|
|
Dynamic equillibrium
|
When a solvent cant hold any more solute the particles escape into solution from the precipitate.At the same time, particles are coming out of solution as solid precipitate. Since this is a continual process and the concentrations do not change; it is called dynamic equillibrium
|
|
|
Soluble
|
A substance that has the ability to dissolve
|
|
|
Mixture
|
When you physically combine two or more pure substances together in a varying ratio
|
