Question

Ionisation isomers [Co(NH₃)₅Br]SO₄ and [Co(NH₃)₅SO₄]Br differ in:
  1. A
    Which group is in the coordination sphere vs outer sphere
    Correct
  2. B
    Number of NH₃ ligands
  3. C
    Oxidation state of Co
  4. D
    Geometry

Correct answer

Which group is in the coordination sphere vs outer sphere

Explanation

Ionisation isomers have same formula but different ions in the coordination sphere vs. the counter-ion (outer sphere). [Co(NH₃)₅Br]SO₄: Br inside, SO₄²⁻ outside. [Co(NH₃)₅SO₄]Br: SO₄²⁻ inside, Br⁻ outside. They produce different ions in solution.
