Lesson details
Key learning points
- Vinegar is an example of an acid that we find in our homes.
- Bicarbonate of soda is a white powder used in baking to make bread, batter and cakes rise when baked.
- When vinegar and bicarbonate of soda are mixed, this produces a new material in the form of carbon dioxide gas.
- The action of acid with bicarbonate of soda is an irreversible change.
- During an irreversible change, the material that has been changed cannot return to its original state.
Common misconception
All bubbles produced contain air and that it is a reversible change.
Teaching slides explain that the bubbles produced when acids react with bicarbonate of soda contain carbon dioxide and that this change is irreversible as a new material is produced.
