Chemistry - Coordination Chemistry Question with Solution | TestHub
Which among the following statement are true for the complex ?
(1) It is a non-electrolyte.
(2) The magnitude of the charge on each complex ion is three.
(3) The complex will not conduct current in aqueous solution.
(4) The complex will exhibit coordination isomerism.
(5) The magnitude of the charge on each complex ion is one.
Options:
Answer:
Solution:
The complex is .
1. It is an electrolyte, dissociating into and ions. Thus, (1) and (3) are false.
2. Oxidation state of Co is and Cr is . The charge on each complex ion is and , respectively. So, (2) is true and (5) is false.
3. Coordination isomerism occurs when ligands are exchanged between cationic and anionic complex entities. This complex exhibits coordination isomerism. So, (4) is true.
Therefore, statements (2) and (4) are true.
