Preparation of alum from aluminum metal by: rachel buckley, alexa kirchharr abstract: the purpose of this experiment, preparation of alum from aluminum metal, was to extract alum from aluminum metal, and to find the percent yield of the alum from the aluminum metal. The major sources of error in the synthesis of alum from aluminum foil include loss of product through various means, human and systematic errors, contamination, and impurities in the reactants.
Experiment 2 - synthesis of alum tutor 1 - balancing redox reactions reactions in which electrons are transferred from one reactant to another are called oxidation-reduction reactions. View notes - lab # 5 synthesis of alum from aluminum from che 1111l-0 at st johns duplicate flammable gas, was a product in some of the reactions 4 what is the trap and what is its purpose in. The history of aluminium has been shaped by usage of alum (hydrated potassium aluminium sulfate, k al(so 4) synthesis of metal davy suggested the metal be named alumium in 1808 and aluminum in 1812, thus producing the modern name other scientists used the spelling aluminium.
