Description
This unit explores empirical formulae, balanced chemical and ionic equations, gas identification, acid reactions, and pH as a measure of hydrogen ion concentration. It covers separation techniques and focuses on planning experiments, accurate measurements, safety, and communicating findings.
This unit builds on pupils’ prior learning from Acids and bases, where they explored the properties and reactions of acids and alkalis. It deepens their understanding by focusing on the formation of salts through reactions between acids and bases, and neutralisation. This prepares pupils for the next unit, Electrolysis, where they will apply their knowledge to separate substances using electric current, reinforcing their understanding of chemical reactions and practical applications of salts and ionic compounds.
