Alum (KAI(SO4)2 xH20] 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 0.7098-g sample of alum is heated to drive off the waters of hydration, and the resulting
KAI(SO4)2 weighs 0.3863 g. Determine the value of x and the complete formula of alum.
Value of x:
Complete Formula:
(b) When 0.7194 g of aluminum is used, 8.592 g of alum forms. What is the percent yield?
