Report Sheet for Experiment 18: "Synthesis" Of An Antacid wa Congratulations! You have just been hired as a researcher by the PRUB Chemical Company. Because of the large number of people eating spicy foods (and often eating them too fast), this company has asked you to develop a new antacid. They have given you some information, but the rest you must discover for yourself. Your boss has suggested that aluminum hydroxide may be effective as an antacid. This compound can be produced by combining aluminum oxide and water. In order to do this reaction, you must first write out a balanced equation: 10 - Al(OH)3 AL03 +3H20_-2Al(OH)3 A U E Water aluminum hydroxide In order to test this antacid properly, you need to make 6500 g of aluminum hydroxide. As you enter your lab to synthesize it, you realize that you need to make a few calculations first. How many grams of aluminum oxide will you need to start with in order to make 6500 g of aluminum hydroxide? (Please show all work!) 6600, Al (OH), Imol Al(OH)s imol Al On 1024 A20, 1978. Al(OH)2 mol Alloh? Im ALO (2) = g aluminum oxide How many grams of water will you need to start with in order to make 6500 g of aluminum

Answer 1

23 1 ALO₂ + 3H₂O = 2.1(OH)3 aluminium oxide Water Aluminium buydroxide we need to prepare 6500gm of a Al(OH)3 molecular weight of Al₂O. & of H2O = {(2x 1) + 163 2 18 gm. n a of M(OH)3 = $26.98 +BX16) +(341)3 277.98gm. from 1 mole of Al2O3 we get a mole of Al(OH)3 6500gm of Al(OH)3 = 6500 more of Al(OH)3 2 83.35 mole of Al(OH)3 for 83.35 more of Al(OH we need 83.35 mileof 1103 83.35 z 41.677 a a = (41.677x 101196) gm of Ahoz To 24249.39 gm of Al2O3 g aluminium oxide. Tagetes 4249.39 To get 2 moles of Allot), we need 3 more of water a 83.35 moles of a aa (3 x 83.35) moles of H20 | Nontott 2 125 moles of Hoa 2 (125x18) gm of 420 2 2950 gm st 420 2250 gm H2O needed
