PART IV. MISCIBILITY OF TWO LIQUIDS
1. For the first two liquids in Table IV-B (the solvents in the
miscibility tests), use the molecular structures provided in the
Introduction to identify each liquid as polar or nonpolar. Put an X
in the appropriate column.
2. For the remaining liquids in Table IV-B, determine if they
are primarily polar, primarily nonpolar, or both polar and polar
based on your observations in Table III-A and based on the polarity
of the solvent....
