Instructional Ideas
- Adapt the microscale approach to other titration labs to minimize time and maximize learning
- Demonstrate the phenolphthalein indicator solution to the class before beginning the titration
Classroom Considerations
- Be sure to emphasize the products of neutralization so learners become comfortable with salts that are not sodium chloride
- Younger pupils may need additional support in writing and balancing equations
Pros
- Simple, homemade burettes are more student-friendly than their expensive glass counterparts
- The instructions are straightforward and include helpful pictures of the apparatus
Cons
- None
