The purpose of the making alum from aluminum lab was to create alum from a series of chemical reactions involving aluminum. Small pieces of an aluminum can were cut and measured before being taken through a series of chemical reactions. This process involved filtering out waste product that was no longer needed in the reaction by using Whatman #4 filter paper and an aspirator. The first reaction that took place was placing aluminum pieces into the strong base NaOH and then heating it. This reaction

LABORATORY REPORT 4 PREPARATION OF ALUM FROM ALUMINUM METAL Huy Nguyen October 2nd‚ 2012 The objective of the laboratory is to synthesize alum (KAl(SO4)2.xH2O) from aluminum powder and to determine the proportion of water in the alum crystals. Alum is a product from the reaction between potassium hydroxide and sulfuric acid. The reaction include several steps‚ as followed: Aluminum powder reacts with potassium hydroxide to generate Al(OH)4- ions and release hydrogen. 2 Al(s) + 2 KOH(aq)

PREPARATION OF POTASH ALUM FROM SCRAP ALUMINUM Introduction Aluminium because of its low density‚ high tensile strength and resistance and resistance to corrosion is widely used for the manufacture of aeroplanes‚ automobiles lawn furniture as well as for aluminium cans. Being good conductor of electricity it is used for transmission of electricity. Aluminium is also used for making utensils. The recycling of aluminium cans and other aluminium products is a very positive contribution to saving
