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 phosphate is a generic term for a variety of salts of sodium (Na +) and phosphate (PO 4 3â). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates.Most of these salts are known in both anhydrous (water-free) and hydrated forms.or example, sodium phosphates are often used as emulsifiers, thickening agents, and leavening agents for baked goods. They are also used to control pH of processed foods.
