Answer:

  • Keq = [ (C₁₉ H₈ Br₄ O₅ S)²⁻ ] [ H⁺ ] / [ (C₁₉ H₈ Br₄ O₅ S) H⁻  ]

Explanation:

The equilibrium expression for the general equilibrium represented by the equation:

  • AB ⇄ A ⁺ + B⁻,

is:

  • Keq = [A⁺] [B⁻] / [AB]

Then, following that sketch, you obtain:

  • Reaction:

        (C₁₉ H₈ Br₄ O₅ S) H⁻ ⇄ (C₁₉ H₈ Br₄ O₅ S)²⁻ + H⁺

  • Equilibrium expression:

         Keq = [ (C₁₉ H₈ Br₄ O₅ S)²⁻ ] [ H⁺ ] / [ (C₁₉ H₈ Br₄ O₅ S) H⁻  ]

The square brackets are used to mean molar concentration (molariy).
