Question

The primary and secondary valancies of cobalt
in the complex ion CoCl3.6NH3 are
O 4,3
O
4,4
O 6,3
O 3,6​

Answer 1

Answer:

Explanation:

Complex CoCl  

3

​  

⋅5NH  

3

​  

 has octahedral structure so atleast one Cl  

−

 ion satisfies primary valency of cobalt(III) and remaining chloride ions satisfies secondary valency.
