A Microscale Acid-Base Titration

This A Microscale Acid-Base Titration lab resource also includes:

Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of the sodium hydroxide solution used in the experiment.

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
