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...
