Topic C3.3: Types of chemical reactions (OCR Gateway A GCSE Combined Science)

This bundle of 4 lessons covers the majority of the content in the sub-topic C3.3 (Types of chemical reactions) of the OCR Gateway A GCSE Combined Science specification. The topics and specification points covered within these lessons include:

Explain reduction and oxidation in terms of the loss or gain of oxygen and the loss or gain of electrons
Recall that acids form hydrogen ions when they dissolve in water and solutions of alkalis contain hydroxide ions
Recognise and describe neutralisation reactions
Write balanced equations for the reactions of carbonates and metals with acids
Recall that relative acidity and alkalinity are measured by pH and describe techniques and apparatus to take these measures

All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.
