Part of the Eduqas GCSE Combined Science curriculum.
Eduqas GCSE Combined Science Topics 6–7 Metals and Acids is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the Eduqas specification (Eduqas GCSE (9–1) Combined Science (C430) – Concepts in Chemistry, Topics 6–7: Reactivity series and extraction of metals; Chemistry of acids). It covers the reactivity series, oxidation and reduction, extracting metals and the blast furnace, electrolysis of molten compounds, electrolysis of aqueous solutions, using metals and biological extraction, acids, alkalis and pH, making salts and titration and strong and weak acids and concentration, then brings it all together with mixed retrieval and exam practice.
There are 29 short steps of about 15 minutes (roughly 7.5 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Reactivity series, Positive ion, Oxidation, Reduction, Ore, Reducing agent, Electrolysis, Electrolyte, Aqueous solution, Competing ions, Low density and Corrosion.
