Unit 3 Solutions, Acids, and Bases

Solutions, especially of the liquid variety, are everywhere. All fresh water in streams, rivers, and lakes, salt water in the oceans, and even the rain that falls from the sky are examples of solutions. In general, what we call “water” is a solution that is essential to life. The characteristics of natural water can be quite complicated.
