Write the equilibrium expression for this reaction: (c19h8br4o5s)h– ↔ (c19h8br4o5s)2– + h+

Explanation:

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

is:

Then, following that sketch, you obtain:

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

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

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