Year 10 Chemistry Unit 4 - Chemical changes
At KS3 students will have learnt about the reactivity series of metals and how this relates to the methods of extracting them from their ores. They will have used acids and alkalis to determine how reactive a metal is and they will also have carried out neutralisation reactions to produce salts.
This unit builds on work from year 9, students will relate the reactivity of a metal to its electronic structure and its position in the periodic table. They will use ionic equations to write about the oxidation and reduction of various substances.
There is plenty of opportunity to build on earlier neutralisation work and students will be required to plan and carry out practical work to produce a pure dry sample of a soluble salt
