Allumina

• Acid: Dissociates (separation of ions) in water to form H+ ions.

  
  

  HCL -> H+ + Cl-
• Base: Substance that reacts with acids to form salt and water.
• Alkali: A base that dissolves in water to form OH- ions.
• Amphoteric: Can act as both an acid & base.

  -> Alumina (Alumina Oxide)

  ->Al2O3

  • Chemically inert except in certain condtions: hot acid & base
• Amphoteric reacting with acid

  
• Uses of Alumina

  • It's chemically inert/nonreactive
  • -> Making it very useful in: filler, paints, sunscreens, glass, stationary phase in chromatography, effective desiccant (drying agent).
