The most abundant aluminum compounds are aluminum oxide and aluminum hydroxide, and these are water insoluble. Aluminum oxide may be present in water both in alkalic form (2Al 2 O 3 (s) + 6H + 3+ (aq) + 3H 2 O (l)) and in acidic form (2Al 2 O 3 (s) + 2OH - 2 - (aq) + H 2 O (l)).An example of a water soluble aluminum compound is aluminum sulphate with a water solubility of 370 g/L.iver water generally contains about 400 ppb of aluminum. Aluminum mainly occurs as Al 3+ (aq) under acidic conditions, and as Al(OH) 4 - (aq) under neutral to alkalic conditions. Other forms include AlOH 2 + (aq) en Al(OH) 3 (aq).
Pure aluminium is soft and weak, but it can form alloys with small amounts of copper, magnesium, manganese, silicon, and other elements to make alloys having a variety of useful properties. These alloys form vital components of aircraft and rockets. When aluminium is evaporated in a vacuum it forms a coating that reflects both visible light and radiant heat. These coatings form a thin layer of protective aluminium oxide that does not deteriorate as silver coatings do.
