An initially pure water sample is exposed to a gas phase containing hydrogen sulfide gas at a partial pressure of 10-4.82 atm at 25 °C. a) Prepare a logC-pH diagram for this system that shows the concentration of H*, OH",H₂S(aq), HS (aq), and S₂ (aq) over the pH range of 4-12. b) Determine the equilibrium pH of this water sample.
