# Why is distilled water such a poor conductor of electricity?

Water is composed of hydronium ions and hydroxide ions. Since ions do conduct electricity, why is distilled water such a poor conductor of electricity?

Water is not composed of these ions. There is ongoing autodissociation equilibrium reaction$$\ce{2 H2O <<=> H3O+ + OH- }$$ shifted strongly toward left, with concentration of ions $$\pu{1e-7 mol/L}$$ at $$\pu{25 ^{\circ}C}$$ .
