Biocomplexity Lab Activity: Measuring Water pH
Learners test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.
Curated OER
The pH scale
Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.
