Water is often described as the universal solvent because it has the ability to dissolve most materials. Of all the substances on earth, only liquid ammonia is capable of dissolving more substances than water. This presents an interesting challenge for researchers and engineers concerned about water quality because water can dissolve and retain traces, often microscopic, of almost any substance.
In this lesson, students will examine how the polarity of a solvent (such as water) can affect the behavior of the solute.
