I am curious to know if bones generally are harder to corrode than human skin in our world and at what rate?

I was thinking to compare how a skeleton would react to corrosion compared to a regular human. Maybe some chemists or the likes had any insight to this. I see many fantasy universes incorporate "acid" as an element but neglect bases and corrosions as a whole.

Bonus question, is it possible to find a list on how different metals react to strong acids and bases. I have heard of the Reactivity series, but not much beyond that, or perhaps I just don't understand how to use it. 
I should note my level in chemistry is very basic, so I hope anyone can enlighten me. 

P.S.
I can clarify. Let's say someone were to splash some strong base/acid on a substance made of bone vs. human skin tissue, then which of the two materials would have the best chance to not be "eaten" so to say. I know it is a bit of an open question. I can also rephrase my metal question: If a person was to make an armor suit of any metal of his/her choice which would than be best at not being "eaten" by the acids/bases?
