Question

Write the equilibrium expression for this reaction: (C19H8Br4O5S)H– ↔ (C19H8Br4O5S)2– + H+

Answer 1

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

Step-by-step 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).
