Action of Heat on Aluminium Hydroxide
When aluminium hydroxide (Al(OH)3Al(OH)3) is heated, it undergoes thermal decomposition to form aluminium oxide (Al2O3Al2O3) and water (H2OH2O). The reaction can be represented as: 2Al(OH)3→ΔAl2O3+3H2O2Al(OH)3ΔAl2O3+3H2O Detailed Steps of the Reaction: Initial Heating: Upon initial heating, begins to lose water molecules. This process starts at relatively low temperatures around 180-200°C. Formation of Aluminium Oxide: As the temperature increases, more water is released, and converts to aluminium oxide. The complete conversion typically occurs at temperatures around 300-400°C. Characteristics of the Decomposition: Endothermic Process: The decomposition of AL(OH)3 is endothermic, meaning it absorbs heat from its surroundings during the reaction. Release of Water
