So, I've been studying the reduction-oxydation reactions and I've wondered if the reducter gets fully ionised when introduced with an oxydant even though it's in excess. Yeah, I tried my best to explain what I meant, sorry if the question isn't clear enough. thanks.

So if the reducing agent is in excess is pretty much a limiting reactants problem.
Say you have the oxidation of Fe in an oxygen-starved environment. When the reaction goes to completion you will have some Fe²⁺ but also some Fe, there wasn't enough oxygen to react with in the first place.
