Sodium burns in chlorine, 5 of 5. A small piece of sodium metal (Na) is dropped into a flask filled with chlorine gas (Cl2). The flask has a layer of damp sand for protection of its glass bottom and to initiate the reaction. Sodium first reacts with water and becomes hot enough to start reacting with chlorine. It burns with a bright yellow light, produces heat and white fumes of sodium chloride (NaCl): Na + Cl2 -> NaCl.
