Ammonium aluminum sulfate

Beginning in the 1700s and beyond, scientists suspected that an unknown metal existed in alum. Alum is found in the form of several compounds—for example, aluminum ammonium sulfate [A1NH IS0 )j 12H20], aluminum potassium sulfate [AlK(SO )2 12HjO], or aluminum sulfate [Alj(SO ) j]. The scientists problem was that they had no techniques or knowledge of how to extract the metal from its ore until 1825 when the Danish chemist Hans Christian Oersted (1777-1851) isolated a very small amount of aluminum by melting alum with potas-... [Pg.179]

Alum Ammonium alums are those alums, such as aluminum ammonium sulfate A12(NH4)2 (804)4 24H20, ferric ammonium sulfate Fe2(NH4)2< S04)4 - 24H2O, chromium ammonium sulfate Cr2(NH4)2 (S04)4 24H2O where ammonium sulfate is crystallized with the heavier metal sulfate. [Pg.86]

In the final purification processing of aluminum oxide by the Bretsznajder method, the principal product, basic aluminum ammonium sulfate, is contaminated with basic aluminum potassium sulfate. The latter is formed by the hydrolysis of aluminum potassium alum according to the equation... [Pg.178]

Aluminum potassium sulfate belongs to a family of compounds known collectively as the alums. The term alum refers to a double salt that consists of aluminum, the sulfate group (S04), and one other metal. The presence of two metals, aluminum plus one other metal, accounts for the name double salt. Other common alums are aluminum ammonium sulfate and aluminum sodium sulfate. [Pg.53]
