actually pure water doesnt conduct electricity, any salts or impurities dissolved in water enable it to conduct electricity, When salts are dissolved in water, they separate into different electrically charged atoms called ions. Sodium chloride (NaCl), breaks up into positive Na ions and negative Cl ions.
Pure water contains very few ions, so it does not conduct electricity very well. When table salt is dissolved in water, the solution conducts very well, because the solution contains ions. ... When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution.
