For the overall reaction H2S(aq) \(\text { ⇌ }\)2H+(aq) + S2– (aq), the value of Ka is 1 × 10–22. The Ksp for FeS is 4 × 10–19 . What would be the maximum concentration of Fe+2 (aq) ion in a 0.1 M solution of H2S that has has its pH adjusted to 2 by mixing a strong acid with the H2S ?
- 4 × 10–38 M
- 6 × 10–10 M
- 6 × 10–6 M
- 4.0 M
Answer
(D) 4.0 M
