The pH scale can be a confusing topic for students. Negative logarithms? Activities of ions? Proton donor, proton acceptor? What does it all mean!?
Having a fundamental 'feel' for the pH scale can clear up that sense of confusion and our micro lab is here to help! In this mini-activity your students will test the pH of everyday liquids. We've put together a simple list of 5 common liquids to keep it short and sweet.
The activity is designed to take 10-15 minutes and serve as a reinforcement for your discussion. You can easily expand this into a full lab by adding a few more liquids and a few in-depth questions.
The activity and key are available below.
