Question

What effect does increasing the concentration of a dissolved solute have on each on boiling point, freezing point, and vapor pressure?

Answer 1

With respect to a pure solvent....

Explanation:

...a dissolved solute should `"(i) elevate the boiling point"`; `"(ii) reduce the melting point of the solution"`; `"(iii) reduce the vapour pressure of the solution"`...

And the amount of elevation/reduction should be proportional to the NUMER of solute particles in solution, i.e. vary proportionally to the concentration...
