Water is the most unique, important, and interesting chemical. About 66% of the human body is composed of water, and approximately 71% of Earth’s surface is covered in water. Water is required to sustain life. Many chemical reactions take place in water. In this section we will classify reactions as Precipitation, Neutralization (Acid-Base), and Oxidation-Reduction Reactions. Click on a study guide to start.
