This lesson explores what happens in a chemical reaction, ways in which we can identify that a chemical reaction has taken place and how the law of the conservation of mass applies to chemical reactions.
This lesson explores what happens when a substance reacts with oxygen and how to represent these reactions using word equations and diagrams.
This lesson looks at what an acid and an alkali is, how to use simple indicators to identify them and some common hazards associated with using them.
This lesson explores how to use universal indicator to identify a substance as acid, alkali, or neutral based on its pH and why universal indicator is better than simple indicators.
This lesson explores the reaction between metals and acids, how to represent these reactions and word equations, and how to test for the presence of hydrogen as a product of the reaction.
This lesson reviews how to spot evidence of a chemical reaction, oxidation reactions, reactions with metals and acids. Acids and alkalis and the pH scale are also reviewed in this lesson.
This lesson focuses on what happens during neutralisation when an acid and an alkali react, how to represent this as a word equation and how to predict the name of the salt produced in this reaction.
This lesson focuses on the techniques involved in carrying out titration reactions and how to use reproducible data to write a conclusion.
This lesson looks at how to plan an investigation into determining which is the best antacid medicine.
This lesson looks at how to check results for reproducibility, how to display results of the antacid investigation appropriately and how to use these results to write a conclusion about which is the best antacid medicine.
This lesson looks at the life and work of the inspirational chemist, Helen Sharman, who went from a being a chemist for the Mars chocolate company to the first Briton in space!
This lesson revisits neutralisation reactions and naming salts, what makes data reproducible and drawing conclusions from data.
