solution
|
a mixture with the same composition, color, density, and taste througout
|
|
solute
|
substance being disolved
|
|
solvent
|
substance dissolving
|
|
alloy
|
made by melting solid substances together
solid solution |
|
dissovling
|
occurs on surface of liquid
|
|
solid into liquid
|
water molecules cluster around other molecules. neg/pos ends attaract pulling other molecules in. break apart. water fills in gaps
|
|
gas into liquid
|
dissolving evenly thoruhoug solution
|
|
rate of dissolving
|
stirring:
brings more solute to solvent smaller crystals increases surface area on surface so more reaches solvent increase temperature |
|
gases; increase rage of dissolving
|
increase pressure
(less pressure bubbles out) cool temperature (compresses gas) |
|
dissovling w/out water
|
nonpolar molecules don't attract water
ex. oil |
|
alchol
|
polar and nonpolar ends
|
|
soap
|
polar end connects with water, making it foam
non polar end attacks dirt. |
|
solubility
|
maximum solute that can be dissolved at a certain temperature
|
|
concentration
|
large amount of solute dissovled ina solvent
|
|
dilute
|
small amount ofsolute dissovled
|
|
saturated
|
can't hold anymore solute at given temperature
|
|
unsaturated
|
can dissove more at given temp
|
|
supersaturated
|
contains moe solute than saturated at same temperature
|
|
ions
|
n fluids around body and cells
|
|
electrolytes
|
compounsd that produce ions in water
|
|
nonelectrolytes
|
don't produce ions in water
|
|
ion solutions
|
They must be broken apart
Ionization Water surrounds molecule and pulls them apart Forming positive and negative ions |
|
dissociation
|
ionic solid seperates into poisitive and negative ions
(ions attaracted to solution by water) |
|
solute affects freezing point
|
Substance freezes
Particles are rearranged in orderly pattern Added particles interfere with this formation Harder to freeze |
|
solute affects boiling point
|
Substance freezes
Particles are rearranged in orderly pattern Added particles interfere with this formation Harder to freeze |
|
car radiators
|
Antifreeze distributed evenly
Fewer water can reach the surface and evaporate |
|
hydrogen bond
|
weak, but lot of them powerful
|
|
oil/water
|
oil less dense than water. when mixed oil rises to top
|
