12.87 Match the diagrams with the following: (12.1)
a. a polar solute and a polar solvent
b. a nonpolar solute and a polar solvent
c. a nonpolar solute and a nonpolar solvent
c
Interpretation:
The problem shows two diagrams with different type of solute-solvents.
Concept introduction:
- Like dissolves like is typically true between species
- Polar-polar solvents will always mix as well as Nonpolar-nonpolar solvents
- Nonpolar-Polar mixture will never mix, will form two phases.
To Match:The diagrams which shows the best option.

Explanation of Solution
There are different type of interaction between polar-polar, nonpolar-nonpolar and nonpolar-polar species. Therefore, one must ensure that the solute and solvent are well defined.
The solute is always in smaller amount than the solvent. Image (1) states an uniform mixture of species, whereas image (2) shows two phase, no mixture.
For any given mixture, there must be then either a polar-polar or a nonpolar-nonpolar solute/solvent system.
Image (2) shows the only combination possible, a nonpolar-polar mixture.
Always ensure to identify the solute, solvent and the type of interaction between them.
