What is the test for halides? How can dilute and concentrated ammonia solution be used for halides? How do hydrogen halides react with water? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 2 – WCH12, but it can also be used for all UK exam boards. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides (which are best opened on Microsoft PowerPoint) is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – Reminder of the test for halides and the colours of the precipitates formed
Slides 4 – 8: explains the importance of ammonia solution to better distinguish between the different precipitates
Slide 9 – students encouraged to predict the colours of precipitates formed by fluoride and astatide
Slide 10 – Details of the reaction takes place when silver chloride dissolves in dilute ammonia solution. The same complex is formed when any silver halide reacts with ammonia solution
Slide 11 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click
Slide 12 – How do hydrogen halides react with water? Equations with protons represented as hydronium ions are also presented to students
Slides 13 – 18: how do hydrogen halides react with water? Students can watch the embedded videos of the hydrogen chloride – ammonia experiment and use the predict-observe-model (POE) model to help them engage with the video demonstration. Alternatively, you could do the demonstration for them in class and use the POE model.
Slides 19 – 26: Exam questions with mark scheme answers (included with the purchase of this resource)

Edexcel International A level Chemistry - lessons with questions and answers | Topic 8 | Redox Chemistry and Groups 1, 2 and 7

This bundle is comprised of 17 PowerPoint lessons covering Topic 8 – Redox Chemistry and Groups 1, 2 and 7 for the Edexcel International A level Chemistry course. The PowerPoints are as follows: 1. Redox and Oxidation Numbers (including electron gain and loss) 2. Oxidation Numbers and Nomenclature 3. Constructing full ionic equations 4. Reactions of group 1 metals (including trends) 5. Reactions of group 2 metals 6. Oxides and hydroxides of group 1 and 2 7. Thermal stability of compounds in group 1 and 2 8. Tests for cations (includes flame tests and test for ammonium) 9. Trends in group 7 10. Redox reactions in group 7 11. Reactions of halides with sulfuric acid 12. Further reactions of halides 13. Making a standard solution 14. Performing a titration 15. Titration Calculations 16. Mistakes and Errors 17. Errors and Uncertainties Each lesson is exactly that . . . a lesson. There is a starter slide, lesson objectives slide, introduction of new knowledge slides, worked examples and then opportunities for students to try independent practice through mini plenary tasks comprised of several questions of graded difficulties. Questions are interspersed through the lessons at regular intervals and always have answers that animate on to the screen when you click. THESE ARE NOT THE INFORMATION ONLY TYPE SLIDES THAT SOME PEOPLE SELL, which are useless for delivering a lesson. We are a team of teachers, and these lessons have been made by actual Chemistry teachers who currently teach in secondary schools in England. We know exactly what you need, trust us. Every lesson has exam questions included as word documents which were made using Exam wizard. The mark scheme and examiner’s report is at the end of the exam question and the answers have been screen shotted and pasted into the PowerPoint at the end. All the slides in every lesson are fully animated and include answers to every mini plenary question and exam question.
