Lesson details
Key learning points
- Gently heating the acid speeds up the reaction, ensuring all acid reacts.
- The salt should be dried using an appropriate method (using filter paper, or in the oven).
- A pure sample should be prepared with equipment washed with distilled water to avoid contamination.
- Reacting a metal hydroxide with an acid also produces a salt and water.
- Reacting a metal carbonate with an acid can produce a desired salt with water, as well as carbon dioxide gas.
Keywords
Method - Describes how an experiment is carried out; it is a step-by-step procedure.
Apparatus - A piece of equipment that is designed for a particular use.
Evaluate - To evaluate something is to make a judgement about it with respect to a particular purpose.
Adapt - To make suitable for use or purpose, e.g. equipment or steps in an experimental procedure.
Common misconception
Pupils can sometimes mistake the excess base for the salt formed as it is a solid.
Emphasise at the beginning of the experiment what soluble means and that the salt will be initially obtained dissolved in water.

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.
