I have a question from my "Inorganic Complexes" workbook.
Aqueous sodium hydroxide solution is added to a solution of iron (II) chloride. A dirty-green precipitate appears which is insoluble in excess sodium hydroxide. Write an equation to show the reaction taking place, and state the type of reaction taking place.
Yeah, I don't really know if I am overthinking this because it's a topic I'm new with, but I am not sure whether to write the iron (ii) chloride as a complex ion, and I don't know what type of reaction it would be. I know it could be acid-base (deprotonation) or ligand exchange. I'm also pretty sure that the precipitate is Fe(H2O)4(OH)2
Help/explanation is greatly appreciated, as I'm feeling slightly out of my depth here.
