UNIT

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.

Indicators of a Chemical Reaction

This lesson explores what happens when a substance reacts with oxygen and how to represent these reactions using word equations and diagrams.

Oxidation

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.

Acids and Alkalis

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.

pH Scale

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.

Metals and acids

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.

Revision 1

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.

Neutralisation

This lesson focuses on the techniques involved in carrying out titration reactions and how to use reproducible data to write a conclusion.

Simple Titrations

This lesson looks at how to plan an investigation into determining which is the best antacid medicine.

Antacid Investigation: Planning

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.

Antacid Investigation: Analysis & Conclusion

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!

Case Study of Helen Sharman

This lesson revisits neutralisation reactions and naming salts, what makes data reproducible and drawing conclusions from data.
