Solubility of Polar Solutes


Ammonia Dissolves in Water:

Polar ammonia molecules dissolve in polar water molecules. These molecules mix readily because both types of molecules engage in hydrogen bonding. Since the intermolecular attractions are roughly equal, the molecules can break away from each other and form new solute (NH3), solvent (H2O) hydrogen bonds.


Alcohol Dissolves in Water:

The -OH group on alcohol is polar and mixes with the polar water through the formation of hydrogen bonds.

A wide variety of solutions are in this category such as sugar in water, alcohol in water, acetic and hydrochloric acids.
