Product Details

Introduce acid–base titrations in a very unique way. This green chemistry version of a strong acid–strong base titration, developed in partnership with Beyond Benign, uses wood ash, a renewable source of base that can be recovered from combusted wood and organic materials, instead of sodium hydroxide. Students extract base from the wood ash by wet methods and then determine the base potential compared to NaOH.

This lab allows students to explore the concepts of acid–base chemistry and indicators in the context of green chemistry and sustainability at a time when climate change is becoming increasingly important to our planet’s health. Includes reproducible student handouts, Teacher Notes and all necessary chemicals.

Complete for 30 students working in pairs.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-ESS3-3. Create a computational simulation to illustrate the relationships among the management of natural resources, the sustainability of human populations, and biodiversity.
HS-LS2-7. Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
