Description
- Define acid and base
- Perform an acid-base titration on microscale
- Verify acidity of vinegar sample meets FDA standards
Grades 9–12. Students explore the characteristics of acids and bases, relate pH values to the concentration of hydronium and hydroxide ions, and conduct neutralization reactions. These explorations gain a real-life connection when students next examine household substances. In the final activity, they design experiments to test vinegar samples for compliance with FDA standards.
Part of the Inquiries in Science™ series. Materials are sufficient for 30 students working in groups of 3.
