Synthesis of Alum (Potassium Aluminum Sulfate) from Aluminum Aluminum cans can be recycled to make potassium aluminum sulfate dodecahydrate, KAK(SO)12H20, which is abbreviated to "alum". The 12 waters are part of the overall formula. Alum can be used to make dyes, printing fabrics, making paper, adhesives, pickling of food and vets use it to induce a dog to throw up. x 1 rxn 2 run 3 The following are the four reactions that lead to alum: Al(s) + 2 KOH...

SYNTHESIS OF ALUM If 500g of laboratory grade aluminum potassium sulfate cost $8.25, is it cost effective to make the aluminum potassium sulfate yourself? Consider the following data and the percent yield(68.6%) when determining the answer. Al foil cost $1.69 for 20 sq-ft and 1 square foot weighs 3.75g. Sulfate acid solution, 3M cost $9.80 for 500mL. Potassium hydroxide solution, 3M costs $12.80 for 250mL. When calculating the answer, only consider the amount of chemical needed and not the capital...
