Sodium chloride dissolves in water forming sodium chloride solution:
Because the forces of attraction of the water poles are stronger than the forces of attraction between sodium ions and chlorine in the sodium chloride fraction where the positive water hydrogen attracts the chlorine ion (CI-) towards it and the oxygen of the negative water attracts the negative water ion that attracts Na + ion towards it.
