Episode 8 — Acids and Bases

Theories of

Learners will be able to:

• Identify acids and bases according to the Arrhenius theory as substances that deliver hydrogen ions (H+) and hydroxide ions (OH-) respectively in aqueous solutions. • Explain how acids and bases react in neutralisation reactions to form water and a corresponding salt, using examples such as hydrochloric acid reacting with sodium hydroxide. • Define a Bronsted-Lowry acid as a substance that donates protons (H+) during a reaction. • Identify the acid and base in a given reaction equation according to the Bronsted-Lowry theory by determining which substance donates or accepts protons. • Explain how water can act as both an acid and a base, depending on the context of the reaction.
