PRE-LAB QUESTION: I. The two unknowns will be selected from this group of solvents: NV
CH3OH Methanol Write out all possible combinations of solvents. Assemble all relevant analytical data: boiling
point, formation of azeotropes, refractive indices, miscibility with water. Use the Table of Solvents (page 26), Miscibility Table (page 34) and the Handbook of Chemistry and Physics.

MISCIBILITY TABLE
The dark squares indicate that the pair of solvents is immiscible. Immiscible pairs of solvents can however
dissolve in each other to an appreciable extent. An example of this phenomenon is the diethyl ether/water pair. This
is why it is necessary to "dry" ether which has come into contact with water. Conversely, small volumes of ether
will "disappear" into large volumes of water.
