Question

Therefore, you know the contents of the four bottles, but do not know which bottle belonged to which compound. The names on the labels are: frans-1,2-dichloroethylene, c/s-1,2-dichloroethylene, cyclooctane, and acetic acid. Without determining the boiling point, you can identify the contents of each bottle using the procedures outlined in Parts I through III of Experiment 4. Outline how you would go about doing this and at what point (Part I, II or III) you could identify each unknown. What effect would you expect each of the following to have on the boiling point and freezing point of water? Explain your answer in some detail.

Explanation / Answer

a)since table sugar dissolve in water and the vapor pressure of water decreases and the boiling point of water increases.

addition of solute to solvent reduces the chemial potential and hence the reduction in Freezing point

b) when marble is added, all the heat is taken by marble leading to increase in boiling point and decrease in Freezinng point.
