HSC Chemistry Module 6 – Acid-Base Reactions

Module 6: Acid/Base Reactions is the second module of the new NSW HSC Chemistry curriculum.

In this module, students will explore the different properties and uses of acids and bases. Ideas that will be explored in section will include acid-base models, naming acids, buffers, and titration.
