How could you dissolve more solid solute in saturated solution in liquid solvent?
Increasing the temperature the solubility increase.
How could you compare a saturated solution to an unsaturated solution?
In a saturated solution, if you add any more of the substance that the solution is saturated with, it will either not dissolve or cause some of the existing solute to precipitate or separate. The one caveat is that it is possible to achieve a "supersaturated solution" by careful manipulation of a solution to bring it into a metastable state. One common way to achieve supersaturation is to cool a saturated solution in a container which is so smooth that it lacks nucleation sites.
What is the difference in saturated and supersaturated?
no
What could you do to change an unsaturated solution to a saturated solution?
Keep adding solute until the solvent cannot disslove any more at that given temperature.
What would happen to a saturated solution if cooled in the refrigerator?
If it is saturated with a solid solute, you would expect some of the solid to precipitate out - as long as the solid could find a surface to nucleate on. If it is saturated with a gas, you would expect more gas to dissolve into it as long as it was still in contact with the saturating gas in the gas phase.

What is the difference between an unsaturated solution and a saturated solution?
An unsaturated solution has excess solvent and can still dissolve more solute.A saturated solution cannot dissolve any more solute, it will simply stay separate.
What effect does temperature have on the solubility of a gas solution in a liquid solvent?
the solubility of a gas decreases when the temperature increases
Solution in which more of the solute could be dissolved at the same temp is called what?
This is a non-saturated solution.
Is a saturated solution necessarily a dilute solution?
A saturated solution contains as much pof the dissolved material as possible. A dilute solution is almost the opposite, it has only a trace of the dissolved material and the solution could contain much more.
What is the difference in saturated and supersaturated?
no
Is a Solution that holds more solute than it normally would be saturated solution?
No, if it holds MORE than it should it is supersaturated.The term supersaturation refers to a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.Saturation is the point at which a solution of a substance can dissolve no more of that substance (under normal circumstances) and additional amounts of it will appear as a precipitate.
How could you use the property of solubility to help identify a type of matter?
Testing by solubility may be a qualitative evaluation of a substance or is used for differenciation of compounds. But it is not a true identification method.
Why is solubility a physical change?
While solubility is undergoing changes in their substances wheather it could be from a mechanical deformation, exposure to another substance, or any of a number other alterations. If the same substance remains after the change, a physical change has taken place.
How could you demonstrate that a sugar solution is just saturated?
You can keep adding sugar, if it dissolves it is still unsaturated and if it piles up at the bottom of the glass it is saturated. you can also freeze the solution or cause it to precipitate
What does any point above a solubility curve represent?
Unsaturated solutions - more solute could be dissolved at the temperature. The solubility curve indicates the concentration of a saturated solution- the maximum amount of solute that will dissolve at that specific temperature. Values below the curve represent unsaturated solutions - more solute could be dissolved at that temperature. Values above the curve represent supersaturated solutions, a solution which holds more solute that can normally dissolve in that volume of solvent.
