Develop critical skills and understanding of Acids and Bases

Available in


The Acids and Bases program is aligned to Module 6 of the NSW syllabus. Students will cover IUPAC nomenclature and reactions of acids, Arrhenius and Bronsted/Lowry definitions of Acids and Bases, strength of acids and bases, pH calculations, buffers and titration. This is a critical component of the final examinations for Chemistry.
