How many ions obtain after dissociation of this complex [ Co ( NH ₃ )₆ ] Cl ₃ ?

Options

  1. A3
  2. B2
  3. C5
  4. D4

Correct answer

D. 4

Step-by-step solution

Primary valency of coordination compounds are ionisable. Thus, dissociation of the complex, [ Co ( NH ₃ )₆ ] Cl ₃ takes place as follows [ Co ( NH ₃ )₆ ] Cl ₃ [ Co ( NH ₃ )₆ ]²⁺+3 Cl ⁻ Therefore, total number of ions obtain will be 4 .
