Unit 10: Acids and Bases—The Voyage of the Proton


Unit Overview

Acids and bases result from the movement of a hydrogen ion—a positively charged single proton, whose electron has been stripped away. The acidity of a solution is based on its concentration of hydrogen ions and is measured on the pH scale. Many reactions must happen in a certain pH range, and buffers can help control the pH. This is especially evident in the human body, where the blood acts as a buffer for the many chemical reactions that occur in it. Whether it is manipulating the pH of the soil to control the color of hydrangea flowers or meticulously controlling ingredients to bake the perfect pastry, acid-base chemistry is all around us.
