Acids, Bases & Salts – Lesson & Worksheet

Edexcel IGCSE Chemistry | Unit 2.34–2.38 | Lesson 30

Overview

This comprehensive lesson explores the definitions of acids and bases through proton transfer, introduces solubility rules for salts, and examines the formation of salts through reactions with metals, oxides, hydroxides, carbonates, and ammonia. Structured tasks help students apply key reaction patterns and predict products.

Specification Covered

• 2.34: Know general rules for solubility of ionic compounds in water
• 2.35: Understand acids and bases in terms of proton transfer
• 2.36: Understand that an acid is a proton donor and a base is a proton acceptor
• 2.37: Describe the reactions of acids with metals, bases and carbonates to form salts
• 2.38: Know that metal oxides, hydroxides, and ammonia can act as bases; alkalis are soluble bases
