Add all four reaction steps together to get the overall reaction. Remember to cross out anything that occurs on both the reactant and product sides and to combine like terms.
1. 2 Al(s) + 2 KOH (aq) + 6 H2O (l) → 2 KAl(OH)4(aq) + 3 H2(g)
2. 2 KAl(OH)4(aq) + H2SO4 (aq) → 2 Al(OH)3(s) + 2 H2O (l) + K2SO4(aq)
3. 2 Al(OH)3(s) + 3 H2SO4 (aq) → Al2(SO4)3(aq) + 6 H2O (l)
4. Al2(SO4)3(aq) + K2SO4(aq) + 24 H2O (l) →2 (KAl(SO4)2∙12H2O) (s)
For each reactant except water, calculate the number of moles you added (use the stoichiometry of the balanced equation to identify the limiting reactant.
