Hi, how can you explain on a molecular level why a higher % of a weak acid dissociates at really small concentrations?
I can't really visualize which driving forces would push the equilibrium to the right, thus forming a higher % of H+ and would appreciate some help

I think we can see it in this way:the process of dissociating is HAc+H2O==Ac^-+H3O⁺, so the more existence of water makes the balance moves to the right.
