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...
Sulfuric acid (H2SO4) dissolves Aluminum metal according to the reaction: 2 Al(s)+ 3 H2SO4(aq) → Al2(SO4)3(aq) + 3 H2(g) Suppose you want to dissolve an Aluminum block with a mass of 15.2 g. What minimum mass of H2SO4 (in g) do you need? What mass of H2 gas (in g) can the complete reaction of the aluminum block produce? Please Show Work
Balance the following equation: Al(s) + KOH(aq) + H2SO4(aq) + H2O(l) ---> KAl(SO4)2 * 12 H2O(s) + H2(g)
mole ratio Al : ALUM from the balanced overall reaction: 2 Al(s) + 2 KOH(aq) + 22 H2O(l) + 4 H2SO4 → 2 [KAl(SO4)2 • 12 H2O(s)] + 3 H2(g)
Calculate the molar mass of alum, KAI(SO4)2·12H20 (potassium aluminum sulfate dodecahydrate). Type the molar mass without units, to the nearest whole number.
What is the net ionic equation adding KOH drop by drop and what
is the equation when you add too much?
calculate the theoretical yield for the production of alum using the following equation. 2 Al (s) + 2 KOH 22 H2O+4 H2So4 2 KAI(SO)212 H2O (s) +3 H2 (g) In Part 2 of this experiment you will qualitatively analyze the composition of alum, KAI(SO4)2-12 H2O (s), by analyzing for AB+, s042-, K+, and H2O. o When 0.1 M BaCl2...
