Lesson Plan: Acidity and Basicity Chemistry • First Year of Secondary School

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define acids and bases, understand their characteristic properties, and identify acidic and basic species in chemical reactions.

Objectives

Students will be able to

understand the different definitions of acids and bases (and alkalis) (i.e., Arrhenius and Bronsted–Løwry),
define and understand the difference between strong and weak acids or bases,
understand the difference between a strong/weak acid or base and a concentrated/dilute acid or base,
identify common acids and bases (e.g., lemon juice, vinegar, and washing detergent),
identify acids and bases from their molecular and structural formulas,
identify and write chemical equations for the dissociation of acids and bases and reactions involving them,
understand the self-ionisation of water and why it is neither acid nor basic (in its pure form).
