This page is an exercise in determining the freezing and boiling points of water
solutions.
When
you
press "New
Problem" a
solute
formula
appears in the first cell and values appear in the next two cells. Determine
the values of the freezing and bioling points of the solution, enter them into
the cells and press "Check Answer." Results appear in the second table.
Hints
Be careful about dissociating solutes (i.e. the van't Hoff i factor!)
All solutions are treated as ideal. kfp(H2O) = 1.86 °C/m, kbp(H2O) = 0.512
°C/m
It is assumed there are not additional processes beyond the possible solute dissociation, such as weak acid/base reactions.
Since browsers are inconsistent with regards to displaying mathematical symbols
the letter "d" will be used to represent the delta sign in the answer.
Pressing "Show Answer" will cause the correct answer to appear and you will no longer be able to submit an answer for that problem.
