Acids, bases, and pH

A free module for the new Regents exam, Physical Science: Chemistry

You can start with a short check of what you already know. Then you’ll work through six short lessons, about 25 to 35 minutes in all, and can try an exam-style cluster: a few questions about one set of data, then a written answer. Come back on later days for short reviews; you finish the module by answering each of its 21 questions right on later days and working one cluster.

Open it on a phone or a computer. You don’t need an account.
