Chapter 12, Problem 7PE

At $\text{25 °C}$ and standard pressure, a hydrogen sulfide solution can be made by bubbling ${\text{H}}_{\text{2}}\text{S}\left(g\right)$ into water; the result is a 0.11 molar solution. Since ${\text{H}}_{\text{2}}\text{S}\left(g\right)$ is more dense than air a layer of pure ${\text{H}}_{\text{2}}\text{S}\left(g\right)$ at atmospheric pressure will cover the solution. What is the value of Henry’s law constant, and is the solubility of ${\text{H}}_{\text{2}}\text{S}\left(g\right)$ much greater or smaller than other gases mentioned in this section? If so, suggest a reason for the difference. (Hint: What is the pressure of the ${\text{H}}_{\text{2}}\text{S}\left(g\right)$?)
