Question

As the number of solute particles in a given volume of solution increase will:

freezing point increase, vapor press decrease? or vice versa

or

boiling point increase, vapor pressure decrease? or vice versa?


Answers

Neither.
As # solute particles increases, freezing point decreases and vapor pressure decreases.

As # solute particles increase, vapor pressure gets smaller and boiling point gets larger.

I like this statement that summarizes it all.

a. f.p is lowered.
b. b.p. is raised.
c. v.p. is lowered.
