Studied by 96 peoplewhat is homogeneous mixture another name for
a solution
homogeneous mixture
a solution where the particles are in uniform and there is a solvent and a solute
solvent
greater amount, does the dissolving
what way does heat travel
high to low
solute
lesser amount, what is being dissolved
solubility
how dissolvable a substance is
when can solutions mix properly
when both are either nonpolar or both are polar
what is it called if two solutions can mix
miscible
immiscible
when one mixture is polar and the other is nonpolar so they dont mix
henry’s law
if a gas is being dissolved in a liquid, the more pressure you have the more gas you will dissolve
if you want to dissolve a gas would a hot or cold liquid dissolve more
cold liquid
what are the two types of heterogeneous mixtures
colloids and suspensions
what is a heterogeneous mixture
it has two or more phases
how big are the particles in a colloid
between 1 and 1000 nanometers which is small enough to stay in place
what are the two phases that a colloid has
dispersed and continuous
what is the dispersed phase of a colloid
the phase that is being dispersed
what is the continuous phase of a colloid
the phase that is surrounding the dispersed particles
suspension
over 1000 nanometers
what do suspensions do if they are left unattended
separate
if the tyndall effect passes through a colloid will the light scatter or pass through
scatter
what is it called when there is constant motion (microscopic juggling) in a solution
Brownian motion
what are examples of brownian motion
jello, milk, hairspray, paint, glue, mayo, whipped cream, ice cream
what are electrolyes
ionic compounds dissolved in water which now make the water conduct a current
how do you dissolve a gas
add pressure and cool it
dissolving a gas is usually
exothermic
what is the formula for osmotic pressure
pie=MRT
what does pie stand for
osmotic pressure
what does M stand for
molaRity
what does m stand for
molaLity
what does T stand for
temp
how do you dissolve a solid
increase surface area (grind it up), heat it, or stir it
how do you get a supersaturated liquid
you heat the solution to make more spaces and then add more solute and allow to cool
what is the molarity equation
moles/L
what is the molality equation
moles/kg
what is heat of solution
the change in heat when dissolving a solute in a solvent
negative change in heat (- triange H)
exothermic- heat is minusing from solution
positive change in heat (+ triangle H)
endothermic- heat is adding to solution(absorbing)
what are the four colligative properties
freezing point, boiling point, vapor pressure, osmotic pressu
how do non-volatile solute particles affect the boiling point of a solution
it raises the boiling point
how do non-volatile solute particles affect the freezing point of a solution
it lowers the freezing point
osmosis
when a solvent passes through a semipermeable membrane from lower concentration to higher concentration
do colligative properties change based on the number of particles or the type of particles
number of particles
which is NOT an electrolyte: acid, base, colloid or salt
colloid
what is the measure of the chance that particles escape from the surface of a solution called
vapor pressure
what is a mixture of metals called
alloy
