NaCl is a solid, it can be made into a solution and introduced into the circulatory system by IV drip. Xe is a gas and can be introduced into the lungs by adding the Xe to the air being breathed. C'mon. Use your reasoning powers. There is no chemistry involved.

It means that the electrolyte dissociates into its separate ions and the chemistry of the solution is the chemistry of the ions. For example, NaCl, when placed in water, dissociates into Na^+ and Cl^-. There is no NaCl anymore.
