How to Write the Net Ionic Equation for KOH + FeCl3 = KCl

TīmeklisIron is a 4th-period element. It is also a d block element which means the outermost orbital of Fe is the d orbital. In the FeCl3 lewis structure, Fe is +3 oxidation state, so its electronic configuration becomes 3d 5. So, it has five electrons in its d orbital. D has five subsets and Cl is a weak field ligand.
