Solubility Intro Note Flashcards
(19 cards)
Solutions
is a homogeneous mixture, and can be a liquid, gas or solid.
Homogeneous
means that it appears the same throughout, although there may be more than one substance in the solution
ex: Air, Kool aid, Bronze
Heterogeneous
means you can see the different substances
ex: trail mix
Solvent
is any substance that has other substances dissolved in it
Solute
Dissolved in the solvent
What state of matter are solvents and solutes
Solvents and solutes can be either of the 3 states of matter
Pure substances
have fixed composition
you cannot change the ratio of the substance without making a new substance
ex: pure water
Solutions have variable compensation
this means that different ratios of solvent to solute are possible
ex: adding sugar to coffee
Chemical change
can’t be reversed
Physical Change
can be reversed
Aqueous Solution
is a solution in which water is the solvent
miscible liquids
Liquids that readily dissolve with each other are said to be miscible
ex: like water and ethanol
Immiscible
Liquids that do not readily dissolve in each other are said to be immiscible
ex: oil and water
Alloy
is a solid solution of metals.
Alloys give the new combination of metals stronger properties than they would have if they were by themselves.
Solubility
the amount of solute that dissolves in a given quantity of solvent, at a certain temperature
Solubility is different for every solute
Levels of Solubility
Saturated
Unsaturated
Supersaturated
Unsaturated
A solution that is not yet saturated. It can dissolve more solute
Saturated
Formed when no more solute will dissolve in a solution
If more solute were to be added, it would not dissolve.
Supersaturated
A solution that cannot dissolve any more solute, and excess solute is present out of solution
