Alum [KAl(SO4)2·xH2O] is used in food preparation, dye fixation, and water purification. To prepare alum, aluminum is reacted with potassium hydroxide and the product with sulfuric acid. Upon cooling, alum crystallizes from the solution. (a) A 0.4711−g sample of alum is heated to drive off the waters of hydration, and the resulting KAl(SO4)2 weighs 0.2564 g. Determine the value of x and the complete formula of alum. Value of x: Complete Formula: (b) When 0.7339 g of aluminum is used,...
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...

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...
