how can you increase a solid substance solubility in a solution?
raise the temperature
This term/concept describes why grocers spray fruits and vegetables periodically
to make them look fresh
osmosis
what is the reason why icy roads are sprayed with salt in the winter time
the salt lowers the temperature at which the water on the roads will freeze "Freezing
Point Depression"
what do we call the dip at the top of the water level in a graduated cylinder
meniscus
if the maximum amount of solute that can dissolve in 100 mL of water is 24 grams
. what would the solution be called if we forced 26 g of solute in it
supersaturated
this type of solution has particles floating at the top and settled at the bottom
suspension
this phenomenon occurs when a laser passes through a colloid and is also seen
in the path of light caused by your car's headlights on a foggy night
tyndall effect
what is the intermolecular force that binds water and molecules together
hydrogen bonds
why won't water and oil mix
"like dissolve likes" water is polar and oil is non-polar
this type of mixture is cloudy
colloid
why do cooks often add salt to their boiling water
the salt raises the temperature at which water boils and makes the water hotter which
cooks the food faster
the term describes the number of moles in a Liter of solution =moles/L
molarity
this type of solution does not hold the maximum amount of solute that a certain
amount of solvent can hold
unsaturated
when most solutes are dissolved, heat is absorbed. what type of reaction is this
endothermic
what is an excellent solvent for most solutes
water
what does Na1+(aq) mean
.1 moles of Ba(NO3)2 in one liter of solution
it is its molarity or the solution concentration
