List the species present in order of increasing concentration in a 0.1 M solution of H₂S. A)H₂S

Question

List the species present in order of increasing concentration in a 0.1 M solution of H₂S. A)H₂S < HS^- < S^2- B)H₂S < S^2- < HS^- C)S^2- < HS^- < H₂S D)HS^- < S^2- < H₂S E)S^2- < H₂S < HS^-

Quizplus · Accepted Answer

In a 0.1 M solution of H₂S, the concentration of H₂S is the highest, followed by HS⁻, and the concentration of S²⁻ is the lowest due to the weak acidic nature of H₂S and its stepwise dissociation.
