Complete Topic 2h: Chemical Tests Edexcel IGCSE Chemistry 9–1 Bundle 4 lessons

Bundle of 4 fully planned lessons and resources for Topic 2h Chemical Tests Edexcel IGCSE 9–1 Double/Separate Chemistry.
Checklist, key terms, definitions, tech guide, revision PowerPoint, coursebook questions and answers included. Perfect for new and experienced teachers, this resource provides an authentic, ready-to-teach unit requiring no additional preparation. All lessons are contained in one PowerPoint with a consistent, clear structure.

Lessons & Key Content:

1. Gas Tests – methods and observations for hydrogen (squeaky pop), oxygen (relights splint), CO₂ (limewater milky), chlorine (bleaches damp litmus), ammonia (red litmus turns blue), and water (anhydrous copper sulfate).

2. Flame Tests for Cations – colours for Li⁺, Na⁺, K⁺, Ca²⁺, Cu²⁺; using nichrome wire; practical examples and interpretation.

3. Precipitate Tests for Cations – using NaOH to identify Cu²⁺, Fe²⁺, Fe³⁺; ammonia test for NH₄⁺; ionic equations and observation tables.

4. Precipitate Tests for Anions – halides with AgNO₃ (Cl⁻ white, Br⁻ cream, I⁻ yellow); sulfate test with BaCl₂; carbonate test using acid + limewater; ionic equations and exam-style questions.

5. Chemical Tests Review Lesson – mixed retrieval tasks, unknown identification problems, full ionic equations and exam practice.

Each lesson includes starter slides with title, learning goals and tasks, along with key terms, bolded explanations, and content checked against the specification and examination papers. Core practicals or key demonstrations are included where relevant with step-by-step modelling, notes, diagrams and student tasks, blooket and quizzes. The PowerPoint features click-in animations, embedded video links, model questions and answers, and coursebook tasks to support strong conceptual understanding. Plenaries link back to learning goals. A technician guide and full lesson list appear on Slide 2 for easy planning.

Notes:
Slide 1 is repeated for TES display purposes.
Lesson starter slide background is black but PowerPoint colour schemes vary throughout.
Separate Chemistry content is clearly marked and distinguished from Double Award content.
