Is sodium nitrate a hazardous waste?

Waste Disposal: Dispose of waste in accordance with all applicable federal, state, and local regulations. Sodium nitrate subject to disposal regulations: U.S. EPA 40 CFR 262, Hazardous Waste Number: D001. U.S. DOT and IATA: UN1498, Sodium nitrate, Hazard Class 5.1, Packing Group III.

What can you do with sodium nitrate?

Uses. Most sodium nitrate is used in fertilizers, where it supplies a water soluble form of nitrogen. Its use, which is mainly outside of the Western World, is attractive since it does not alter the pH of the soil. Another major use is as a complement to ammonium nitrate in explosives.

Does sodium nitrate explode?

Sodium nitrate appears as a white crystalline solid. Noncombustible but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire.

Can sodium nitrate decompose?

Sodium nitrate (and potassium nitrate) upon heating decomposes to produce sodium nitrite and colorless and odourless oxygen gas. This characterizes the colorless oxygen gas as it rekindles a burning wooden splinter.

Can you pour sodium nitrate down the drain?

Collect powdered material in the most convenient and safe manner and place into sealed containers for disposal. DO NOT wash into sewer. For water spills add Soda Ash and Calcium Hypochlorite to adjust pH to 7. Sodium Nitrite is toxic to aquatic life.

Is sodium nitrate a rust inhibitor?

Sodium nitrite is an anodic inhibitor and as the name implies, anodic inhibitors interfere with the anodic process (metal dissolution), and reduce the corrosion rate by suppressing the anodic reaction, through the formation or maintenance of a passive film on the metal surface.

Why does sodium nitrate explode?

Explosion: Explosive with shock, heat or friction. Sodium Nitrate decomposes explosively when heated > 538C (1000F).

Is sodium nitrate soluble or insoluble?

Commonly referred to as “Chile saltpeter”, this compound consists of a sodium cation (Na+) and a nitrate anion (NO3–). At room temperature, sodium nitrate exists as a white, crystalline solid which is highly soluble in water.

Is sodium nitrate flammable?

Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. Explosion: Explosive with shock, heat or friction. Sodium Nitrate decomposes explosively when heated > 538C (1000F).

What temperature does sodium nitrate decompose?

The kinetics of the thermal decomposition of molten sodium nitrate have been studied as a function of temperature in the range 570–760°. The effect of replacing the air over the reactant by argon has been examined.

At what temperature does sodium nitrate decompose?

around 600 °C
Thermal decomposition of sodium nitrate under isothermal conditions at around 600 °C is sequential reaction, which is NaNO3 → NaNO2 → Na2O.
