Reaction of coloured metal complexes with water and sulfuric acid
I recently started researching the coloured compounds made from transition metals focusing on one with oxidation state II, so Mn,Fe,Co,Ni,Cu and Zn with all of them in hydrated metal sulfate complexes.
I've done some research and found why they have their colours. However I still do not know what metal ligand complex will my compounds will make when reacted with water and concentrated sulfuric acid?
Knowing the end product would help me in formulating the reaction equation and would be easy to understand for the presentation.
