Acid-base reactions (carbonates as bases)
I can identify bases, predict the names and states of products from a neutralisation reaction and compare the properties of metal and non-metal oxides.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- A base is a substance that neutralises an acid to make salt and water only (this is a neutralisation reaction).
- Hydroxides are generally soluble bases (they contain OH⁻ ions).
- Metal oxides are bases that are generally insoluble.
- Non-metal oxides are soluble and form acidic solutions.
Keywords
Base - A substance that reacts with an acid to form a compound called a salt.
Soluble - A way of describing a substance that does dissolve in a particular solvent.
Insoluble - A way of describing a substance that does not dissolve in a particular solvent.
Hydroxide - A basic compound which contains an ion comprising of an oxygen and a hydrogen atom (OH⁻).
Neutralisation - A chemical reaction between an acid and base to produce a neutral solution including a salt and water.
Common misconception
Pupils often believe that acids 'eat' away at substances, e.g. acid rain and limestone, rather than understanding that this is a chemical reaction.
Using familiar reactions between acids and bases, e.g. hydrochloric acid and sodium hydroxide or calcium carbonate, will provide evidence that a reaction has taken place (i.e. a change in temperature or producing a gas).

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
