A typical recommended dose of Adderall is 20 mg/day for adults. If a tablet is dissolved in 100 mL of water, [(Amphetamines)2SO4] = 0.0005M. a. Write out the dissociation reaction of (Amphetamines)₂SO4 in water: b. Sulfate (SO4²-) does not have a significant impact on pH of aqueous solutions, and we can categorize it as a negligible base. Considering the ions you wrote out in part a, predict whether the pH of the solution will be acidic, basic, or neutral. Briefly explain your reasoning. c. What is the pH of a 0.0005M solution of (Amphetamines)2SO4(aq) at 25 °C if the Kb of amphetamine is 1.3 x 10-4?
