Recalling Prior Knowledge
- What makes a water molecule polar?
- What is the difference between a homogeneous and a heterogeneous mixture?
Water is called the universal solvent because it is capable of dissolving so many different things. The geological
processes of erosion and weathering are a direct result of water’s dissolving power. In this lesson, we begin to
examine aqueous solutions and how they form.
