Buffers, the Acid Rain Slayer: Crash Course Chemistry

The video explores the concept of acid rain, its formation, and its environmental impact. It demonstrates an experiment showing how acid affects distilled and river water, highlighting the role of buffers like calcium carbonate in maintaining pH balance. The video explains buffer solutions, acid-base equilibrium, and the importance of buffering in various contexts. It concludes with a demonstration of titration to determine buffering capacity, emphasizing the natural protection mechanisms in the environment.
