The correct answer is Option A.
The purification of alumina can be done by Baeyer's process.
In Baeyer’s process, impure bauxite is converted into pure alumina. The conversion process involves mainly three reactions:
1. Concentrated sodium hydroxide solution is heated with amphoteric bauxite at a temperature of 150 to 200°C under pressure to get sodium aluminate.
2. Sodium aluminate is then diluted with water at a temperature of 50 to 60°C. Thus, sodium aluminate gets hydrolysed to form solid aluminium hydroxide and sodium hydroxide.
3. Finally, dried aluminium hydroxide precipitate is ignited at a temperature of 1100°C to remove water molecules to get alumina.
