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?

The first step in purifying the urine collected on the ISS is to treat every liter of urine with 20 mL of 1.0 M H2SO4. To simplify the calculations, lets assume that urine is water. a) What is the pH of a solution of 20. mL of 1.0 M H2SO4 added to 1.00 L water? To determine this, you can safely assume that 100% of the H2SO4 reacts to form H3O+ and HSO4- ions. Use pKa2 (1.92) to determine if any more protons are added to the solution from HSO4-.
To what final concentration of NH3 must a solution be adjusted to just dissolve 0.035 mol of NiC2O4 (Ksp = 4×10−10) in 1.0 L of solution? (Hint: You can neglect the hydrolysis of C2O42− because the solution will be quite basic.) Express your answer using one significant figure.
