- Alumina is the common name for aluminium oxide.
- It is amphoteric = act as a acid or a base depending on the conditions.
- If an acid, acts as a base, if a base it acts as an acid.
- Aluminium oxides react with hot hydrochloric acid, and it gives aluminium chloride and water.
- Aluminium chloride is soluble (get a aluminium chloride solution)
- AL2O3 + 6HCL -> 2ALCL3 + 3H2O
- Aluminium oxide is chemically inert except under certain conditions (due to this it has a lot of uses, such as paint, sunscreen and glass)
- It is also a effective desiccant and can be used at a range of basic and acidic pHs.
- Group 1 and group 2 meal oxides are basic…
