13.3 Solutions of Solids Dissolved in Water: How to Make Rock Candy 449 e form solutions with nonpolar solutes. For example, you may use paint thinner, a nonpolar solvent, to remove grease from a dirty bicycle chain or from ball bear- ings. The paint thinner dissolves (or forms a solution with) the grease, removing it from the metal. In general, polar solvents dissolve polar or ionic solutes, and nonpolar sol- vents dissolve nonpolar solutes. This tendency is described by the rule like dissolves like. Thus, similar kinds of solvents dissolve similar kinds of solutes. Table 13.2 lists some common polar and nonpolar laboratory solvents. TABLE 13.2 Common Laboratory Solvents Common Polar Solvents water (H2O) acetone (CH3COCH) methyl alcohol (CH,OH) Common Nonpolar Solvents hexane (CH4) diethyl ether (CH3CH OCH2CHs) toluene (C-Hs) CONCEPTUAL CHECKPOINT 13.1 Which compound would you expect to be least soluble in water?
