Pure water (100.000% H2O) is a non-conductor. You may want to demonstrate that water is composed of two elements, gaseous Hydrogen and gaseous Oxygen. You can do this demonstration by sending an electric current through the water -- electrolysis. If you use pure water the reaction will be really slow. However, if you add several drops of sulfuric acid to the water the reaction bubbles right along. Why? Because the sulfuric acid breaks into ions (H+, HSO4- and SO42-) ions. The ions will conduct the electricity to break down the water.

No. There needs to be ions in the solution to carry the electrons to the anode.
