Lesson: Acidity and Basicity Chemistry

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).
