Neutralisation
Narrated lesson · press play
When an acid meets a base, they cancel out — that's neutralisation, and it makes a salt. Learn the ionic equation H⁺ + OH⁻ → H₂O, the four ways acids react with alkalis, metal oxides, hydroxides and carbonates, the test for carbon dioxide, and how to write and balance the equations.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 7.3):
- Describe the reaction of a base/alkali with an acid as neutralisation
- Describe the neutralisation of an acid with an alkali as H⁺ + OH⁻ → H₂O
- Describe neutralisation as one method of preparing soluble salts (e.g. sodium chloride)
- Suggest methods of preparing soluble salts by neutralisation (e.g. copper(II) sulfate, sodium chloride)
- Describe the reactions of acids with metal oxides and metal hydroxides
- Describe the reaction of acids with metal carbonates and the test for carbon dioxide
- Write word and balanced equations for neutralisation with metal oxides, hydroxides and carbonates
