Aluminium Hydroxide

Action of Heat on Aluminium Hydroxide

When aluminium hydroxide (Al(OH)3Al(OH)3​) is heated, it undergoes thermal decomposition to form aluminium oxide (Al2O3Al2​O3​) and water (H2OH2​O). The reaction can be represented as: 2Al(OH)3→ΔAl2O3+3H2O2Al(OH)3​Δ​Al2​O3​+3H2​O 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

Acidity of Aluminium Hydroxide

Aluminium hydroxide, with Al(OH)3Al(OH)3​, is amphoteric, meaning it can act as both an acid and a base. Its acidity or basicity depends on the environment it is in: In Acidic Solutions: can react with acids, acting as a base. For example, it reacts with hydrochloric acid:Al(OH)3+3HCl→AlCl3+3H2OAl(OH)3​+3HCl→AlCl3​+3H2​O In Basic Solutions: can
