Product Details

Proper pH is a true vital sign—in the blood, in the lungs and throughout the body! How do buffers maintain the delicate pH balance needed for life and health? Explore the properties of biological buffers in this two-part kit. In Part 1, students examine the acid–base balance in a model carbonate “blood” buffer. The pH range over which buffers are effective is illustrated in Part 2, where students prepare two different phosphate buffers that reflect the physiological role of buffers within cells. Acid–base theory “comes to life” as students integrate their understanding of biology and chemistry. Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to all questions, and all chemicals and consumable supplies needed to perform the lab.

Complete for 30 students working in pairs. Fifteen reusable, 24-well reaction plates are recommended and available separately.
