Question
Is the complex $[CoF_6]$ cationic or anionic if the oxidation state of cobalt ion is $+3$?
✓
Answer
In the complex, Co carries $+ 3$ charge while $6F^–$ carry $– 6$ charge. Hence the net charge on the complex is$ – 3$.
Therefore it is an anionic complex.
Therefore it is an anionic complex.
