the primary and secondary valencies of the central metal ion in the [Co(NH3)Cl3 

Asked by kasireddyteja15 | 4th Dec, 2019, 09:52: PM

Expert Answer:

The Primary valency is the number of negative ions needed to satisfy the charge on the metal ion.

The secondary valency is the number of ions of molecules that are coordinated to the metal ion. 

 

In [Co(NH3)6]Cl3

The cobalt(III) complexe three Cl- ions are needed to satisfy the primary valency of the Co3+ ion.

In this complex the primary valency is 3; and the secondary valency is 6.
