How concentrated can an acid be? How concentrated can an acid be without it being supersaturated? Is there a certain limit to how concentrated an acid or base can be?

When I mean concentration, I mean molarity; so how concentrated can an acid or base be? 



NOTE: Can be a strong or weak acid/base. Because we are just looking for the amount of solvent needed to dissolve to start the dissociation process.



EDIT: No autoprotolysis please. Acids that need a solvent to dissociate.
I am talking about dissolving in water since an acid needs some sort of solvent to dissociate.


No, it doesn't. You neglect autoprotolysis where the water-free acid itself is the solvent.

\begin{align}
\ce{2H2SO4 &amp;&lt;=&gt; H3SO4+ + HSO4-}\\
\ce{3HF &amp;&lt;=&gt; H2F+ + HF2-}
\end{align}
