Question #758dc

Answer 1

This is `Fe^(3+)` ion.........., i.e. `"ferric ion, Fe(III)"`

Explanation:

`[Fe(C-=N)_6]^(3-)` is the complex ion, that is composed of a `Fe^(3+)` centre, and `6xx""N-=C^(-)` ligands.

Of course, the resultant complex preserves the ionic charge of its consituent ligands and metal centre, and the net charge is `6xx(-1)+3=??`

If the counterion were potassium, i.e. `K^+`, what salt would likely precipitate from solution?
