Many metals dissolve in liquid mercury to form amalgams. Based on the concentration of solute dissolves in a solvent, solutes are categorized into highly soluble, sparingly soluble or insoluble. Hence water is better able to decrease the electrostatic attraction between \(\ce{Li^{+}}\) and \(\ce{Cl^{-}}\) ions, so \(\ce{LiCl}\) is more soluble in water than in acetone. Thus we need to consider only the energy required to separate the solvent molecules (\(H_1\)) and the energy released by new solutesolvent interactions (\(H_3\)). Basically, solubility increases with temperature. A solute can come in many forms. In contrast, a hydrophobic substance may be polar but usually contains CH bonds that do not interact favorably with water, as is the case with naphthalene and n-octane. the first solution is more diluted while the second one is more concentrated. Ultimately, each handful, cup, or scoop removed from one of these mixtures will have a different distribution of ingredients. The solubility has been the extent of the dissolution of the solute in the solvent without being precipitated out. Hydrophilic substances tend to be very soluble in water and other strongly polar solvents, whereas hydrophobic substances are essentially insoluble in water and soluble in nonpolar solvents such as benzene and cyclohexane. Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature.
