capable of being dissolved
homogenous mixtures that are the same concentration for every sample
lower amount being dissolved
higher amount dissolving
why suface area affect speed of dissolution
more suface area is exposed to the solvent and so more solvent touches it at the same time and so increasing the rate.
why mising speeds of dissolution
because stirring makes the outside solvent come in and the ones that already dissovled out at a faster rate and so dissolving it faster.
why increasing temperture speeds dissolution
because temperature makes the solvent molecules more faster and so more collisions between solvent and solute and so dissolving faster
saturated solution
maximum amount
less solute than saturated
super saturated
more than saturated
like dissolves like
substances with similar bondings dissolve faster
not soluable
gas solubility with temperture
temkp goes up solubility goes down
solid solubility with temp
temp goes up solubility goes up
liquids with pressure and solubility
increase pressure = increase gas solubility
number of moles of solute in one liter of solvent
the higher concentration = higher molarity
heat solutions to different boiling points to seperate liquids when liquids evaporate and condense at each boiling pt.
fractional distilliation
getting crude oil gasoline petroleum
how chromatograms are made
solvent spreads solution over paper by attraction of the particles in the ink to the solvent
percent composition
multiply percent by volume and then take that and add water until to the amount you need
volume (solute) / (solvent) x 10^6
ionic solid dissolves and ions seperate
what does ionizatin depend on
the bonds of molecules and attraction of solute and solvent
5 properties of acids
sour taste
change color of ph indicator
some react with metal to produce H2
react with bases to produce salt and water
some conduct electricity
5 properties of bases
change ph indicator
feel slippery
react with acid to produce salts and water
conduct electricity
arrhenius acid
increase the H+ concentration
arrhenius base
increase OH- concentratiion
hydronium ion
how to tell strong or week of arrhenius
number of ions in solution not concentration
bronsted lowry acid
DONATES proton ( start of arrow)
bronsted lowry base
ACCEPTS proton (end of arrow )
Lewis acid
ACCEPTS electron pair
Lewis base
DONATES electron pair
PH + POH =
H30+ x OH- =
1 x 10^-14
