ed chemical equation. However, the balanced chemical equation only works in units of moles. To convert grams of aluminum to moles of aluminum the atomic mass of aluminum must be used. grams of aluminum x 1 mole Al = 1 26.98 g Al To relate the moles of aluminum to KAl(SO4)2* 12H20, the mole to mole ratio must be found in the balanced chemical equation. In this case it is: 1 mole of Al3 = 1 mole KAl(SO4)2 12H20 As...

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...
Show the calculation of (1) the expected grams of alum (KAl(SO4)2 •12 H2O) formed from the reaction of 1.3 grams of aluminum metal and then show the calculation of (2) the % yield if the actual yield of alum is 19.32 grams. Overall reaction is shown below: 2 Al + 2 KOH + 10 H2O + 4 H2SO4 → 2 KAl(SO4)2 • 12 H2O + 3 H2(g)↑
