Question

Pure water does not conduct electricity. Why does adding a few drop of an acid to the pure water make a conducting?

Answer 1

Because water is insulator or we can say that it has high dielectric constant (=permittivity÷permittivity of free space) so it do not conduct electricity , it has no ions (no doubt it has ions but are counted as negligible) to move ; in order to make it ionic (presence of ions) acid is added because according to Arrhenius theory when an acid is dissolved in water,it releases H+ or hydronium ions(H+3O)
