The Henry’s law constant for H2S is 0.1 mole/L-atm. H2S(aq) ↔ HS-(aq) + H+ , where Ka = 0.86 x 10-7. If you bubble pure H2S gas into a beaker of water (meaning the partial pressure for H2S(g) is 1 atm), calculate [HS-(aq)] and [H2S(aq)] at a pH of 5 in moles/L, respectively. Ans: [H2S] = 0.1 M; [HS-] = 8.6 x 10-4 M at pH = 5
