Basic Chemistry Concept Behind Formation of Magnetite

Hi, I’m looking to better understand the mechanisms involved in the synthesis of magnetite by the reduction of ferric chloride using an alakaline solution.

The reaction is this:

FeCl2 + 2FeCl3 + 8NH3OH —> Fe3O4 + 4H20

I know this is a precipitation reaction and that the magnetite is an ionically b…
