NEW AQA GCSE (2016) Chemistry - Making Salts

This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Chemical changes and electrolysis’ SoW.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience

This lesson begins with a definition of a salt and an introduction into chemical reactions between acids and metals to make a salt. Students are shown which salts form from using certain acids and will then need to complete a set of word equations, this work can be self-assessed using the mark scheme included in the PowerPoint.

Students will then need to complete a set word equations for a set of reactions between metals and acid, including the balanced symbol equations with state symbols. Students can either peer or self-assess their work using the mark scheme provided.

The next part of the lesson focuses on ionic equations, students are asked to write the ionic half equations for the reaction between magnesium and hydrochloric acid. Once students have completed this task, the answer as well as an explanation is included in the PowerPoint so pupils can check their own work. Now students are given a set of chemical reactions, for each one they will need to write the ionic half-equations. This work can also be self-assessed using the mark scheme included. To summarise this section of the lesson students will need to complete a fill-in-the-blank task.

The second half of the lesson, pupils will look at the reactions between an acid and a base and be shown how to generate the formulae of salts given the names of the metal or base and the acid. To check their understanding, pupils are now asked to complete a ‘quick check’ task, a set of questions on what they have learnt so far. This work can be self-assessed using the answers provided.

Finally, pupils are shown examples of chemical reactions between an acid and a alkali and acid and carbonates. Pupils will need to answer questions about these two types of reactions, work which can be self-assessed using the mark schemes included.

The plenary task is a ‘Silent 5’ task, pupils will need to write an account of what they have learned in the lesson today, including details of what they have understood well and what they would like to spend more time on.

All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
