Chemical 91ts: Cations & Anions – Lesson, Worksheet & Practical

Edexcel IGCSE Chemistry | Unit 2.47–2.48 | Lesson 35

Overview

This lesson introduces the key qualitative tests for identifying cations and anions in solution. Students explore characteristic precipitate colours, confirm the presence of specific metal or non-metal ions, and apply these techniques in a guided classroom practical.

Specification Covered
  • 2.47: Describe tests for cations – NH₄⁺ using sodium hydroxide and identifying gas evolved; Cu²⁺, Fe²⁺ and Fe³⁺ using sodium hydroxide
  • 2.48: Describe tests for anions – Cl⁻, Br⁻, I⁻ with acidified silver nitrate; SO₄²⁻ with acidified barium chloride; CO₃²⁻ with dilute hydrochloric acid
What’s Included
  • Editable PowerPoint Lesson (Theory + Practical + Tasks)
  • Student Worksheet
  • Step-by-step methods for each ionic test
  • Observation tables and guided review questions
Features
  • Fully aligned with Edexcel IGCSE Chemistry Unit 2
  • Includes visual support for identifying precipitate colours and gases
  • Helps students distinguish between halides and common cations
  • Supports practical lab skills with clear, student-safe instructions
  • Clean and consistent Synapse Science format
