Sodium and Chlorine Reaction - The making of table salt

An Erylmeyer flask is filled will chlorine gas by the reaction of hydrochloric acid and potassium permanganate. Sodium metal is placed into the flask and the reaction is catalyzed when a few drops of water is placed on the sodium metal in the flask. What results is an exothermic reaction that produces a white smoke full of NaCl or sodium chloride dust.
