Question

Hydrogen sulfide (H₂S) is a toxic gas that inhibits cellular respiration. It is a weak diprotic acid and is often produced by anaerobic microbial decomposition of organic matter. A hydrogen sulfide solution has a pH of 5.85. Calculate the concentration of hydrogen sulfide (H₂S), bisulfide ion (HS⁻), and sulfide ion (S²⁻) in the solution assuming that the total concentration of the three species is 2.45×10⁻⁵ M.

Accepted Answer

[H₂S] = 2.29×10^–5 M
[HS^–] = 1.62×10^–6 M
[S^2–] = 1.49×10^–13 M

Answer

[H₂S] = 2.29×10^–7 M
[HS^–] = 1.62×10^–8 M
[S^2–] = 1.49×10^–11 M

Answer

[H₂S] = 1.45×10^–5 M
[HS^–] = 1.18×10^–6 M
[S^2–] = 3.55×10^–13 M

Answer

[H₂S] = 2.12×10^–6 M
[HS^–] = 3.05×10^–7 M
[S^2–] = 4.11×10^–14 M
