ALUMINUM WAICG PRE-LABORATORY QUESTIONS 1. In this experiment, aluminum will be converted into potassium aluminum sulphate dodecahydrate. The process requires three reactions. Balance these three reactions. H2 (a) KAI(OH)4 (aa) Al (s) НОН A] КОН (ag) + + (I) H20 ) KAI(SO4)2 (aa) + H2SO4 (aa) KAI(OH)4 (aa) B] KAI(SO4)2 12 H2O (e) C] KAI(SO4)2 (aq) H20 () + 2. Under experimental proced ures #2 and # 3, the experiment calls for reacting aluminum with water and potassium hydroxide. See 1A above for the equation. A student used the following quantities: a 3.00 grams Al 15.0 mL of 8.00 M KOH 75.0 mL of distilled HOH Which of the reactants is the limiting reactant? answer.) Show your work and set-up.
