Question:
what is it called when a solution has more than the usual maximum amount of solute. is this solution
stable or unstable.
Answer:
supersaturated makes it unstable
Question:
what is an excellent solvent for many solutions.
Answer:
water
Question:
what does molarity mean? What is the formula for finding Molarity? what is the symbol for
molarity.
Answer:
molarity is the concentration of a solution
Question:
explain the process of osmosis.
Answer:
is the process where solvent molecules move through a semipermeable membrane from a dilute
solution into a more concentrated solution
Question:
,what generally increases the solubility of solid solutes in water? what decreases solubility.
Answer:
increasing temp increases solubility and decreasing temp decreases solubility
Question:
this type of mixture has particles that are larger than those in solutions and are, therefore, cloudy in
appearance.
Answer:
colloid is cloudy in appearance because the particles in the solution are larger
Question:
this type of mixture is a true homogeneous mixture.
Answer:
solution- all mixed together, the same
Question:
this word describes a substance that can dissolve in a solvent, such as water.
Answer:
solute, solutes dissolve in solvents
Question:
the path of sunbeams through dusty air or the path of car held light beams on a foggy night are
examples of what effect.
Answer:
tyndall effect
Question:
,when you dissolve solutes, heat is generated(heat of solution). for most solutes, is the process
endothermic or exothermic.
Answer:
exothermic, because heat is being released out of the reaction

, Answer:
first increases then decreases at 4 degrees celsius
Question:
the skin like quality of the surface of water is caused by water's relatively high.
Answer:
surface tension
Question:
Compared to its height in a wide-diameter tube, the height of a column of water in a
narrow-diameter tube will be________________ due to capillary rise.
Answer:
greater
Question:
compared to the specific heat of most materials, the specific heat of water is.
Answer:
much higher
Question:
what is an example of the process of endothermic?
Answer:
vaporization
Question:
Water seldom appears in a pure state on Earth because it tends to.
