Chemical and ionic equations, examples with questions and answers. Lesson objectives: relate ionic and full equations, with state symbols, to observations from simple test-tube reactions, for reactions of acids. 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 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 above) Slide 3 – Recap slide covering acids that students should be familiar with from GCSE level Slide 4 – Acids with metals, including the general equation, symbol equation, ionic equation and exploration as to whether or not it is neutralisation and/or redox Slide 5 – Acids with metal oxides and insoluble metal hydroxides, including the general equation, symbol equation, ionic equation and exploration as to whether or not it is neutralisation and/or redox Slide 6 – Acids with alkalis, including the general equation, symbol equation, ionic equation and exploration as to whether or not it is neutralisation and/or redox Slide 7 – Acids with metal carbonates, including the general equation, symbol equation, ionic equation and exploration as to whether or not it is neutralisation and/or redox Slide 8 – Mini plenary/learning pit stop. Three questions of increasing difficulty to check students’ understanding thus far. Answers animate onto the screen. Slide 9 – Exam questions place holder slide Slide 10 – 20 answers to exam questions per slide If you have a positive experience with the resource please leave a positive review!
