1 Sodium azide is a rapidly acting, potentially deadly chemical that exists as an odorless white solid. 2  When it is mixed with water or an acid, sodium azide changes rapidly to a toxic gas with a pungent (sharp) odor. Breathing the gas that is formed from sodium azide causes the most harm, but ingesting (swallowing) sodium azide can be toxic as well. 2  The gas formed from sodium azide is most dangerous in enclosed places where the gas will be trapped. 3  The toxic gas quickly disperses in open spaces, making it less harmful outdoors.
Sodium chloride /ËsoÊdiÉm ËklÉraÉªd/ , also known as salt, common salt, table salt or halite, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.olid sodium chloride has a melting point of 801 Â°C. Thermal conductivity of sodium chloride as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K (â265.15 Â°C; â445.27 Â°F) and decreases to 0.069 at 314 K (41 Â°C; 106 Â°F). It also decreases with doping.
