Chemistry - Chapter 14

Mixture

Mixture

2 substances combined - not pure

solution

2 substances combined where solute particles are smaller that the solvent

suspension

2 substances where solute particles are bigger than the solvent particles - heterogeneous

colliod

all particles are the same size/no settling

- homogeneous

unsaturated

a solvent that can dissolve more solute - only looks like the solvent

saturated

maximum amount of solute dissolved in solvent

-can see undissolved solute

supersaturated

tricked solution/dissolved more than normal maximum solute in solvent → heat + let cool slowly

Electrolytes

when dissolved the solution conducts electricity better → solutions need ions for electricity to travel

boiling point elevation

add solute to solvent so ions pull down on h2o so it needs increased temp to boil

freezing point deppresion

add solute to solvent so ions get in the way of crystals forming so lower temp to freeze

heterogeneous

mixture where particles of solvent and solute are different sizes

homogeneous

mixture where particles of solvent and solute are same size
