What is sodium azide soluble in?

What is sodium azide soluble in?

WaterSodium azide / Soluble inWater is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides neither food, energy, nor organic micronutrients. Wikipedia

Is sodium azide soluble in acetonitrile?

Sodium azide is soluble in water (40.8 g/100 mL at 20 °C) and ammonia, but insoluble in acetone, ether, chloroform and hexane.

What type of solvent is NaN3?

Sodium azide is the inorganic compound with the formula NaN 3. This colorless salt is the gas-forming component in legacy car airbag systems. It is used for the preparation of other azide compounds. It is an ionic substance, is highly soluble in water and is very acutely poisonous.

What is the importance of adding sodium azide NaN3 during buffer preparation?

Sodium azide (NaN3) is added to prevent microbial contamination. PBS with azide is also useful as a storage buffer.

How do you dissolve sodium azide?

To make a 10% stock solution of sodium azide, dissolve 10 g of sodium azide in 100 ml of distilled H2O.

Is sodium azide stable in water?

WaterSodium azide / Soluble in

How do you quench sodium azide?

Cool down the reaction mixture to 0 deg C and slowly add water to quench the excess sodium azide. just adding water will not destroy the sodium azide, my reaction is in water. If you extract your product first, you can quench the aqueous phase with sodium nitrite and acid without losing your product.

How do you handle NaN3?

If your eye or skin is exposed to sodium azide (NaN3) or hydrazoic acid (HN3), use the emergency eye wash to rinse your eyes for 15 minutes and then seek medical attention. If you swallow or inhale NaN3, seek medical attention immediately; medical emergency is needed with severe shortness of breath.

Is NaN3 acidic or basic?

NaNO3 is neither an acid nor a base. It is made from the neutralization reaction of the strong acid, namely Nitric acid (HNO3) with a strong base, namely Sodium hydroxide (NaOH). The pH value of the aqueous solution of NaNO3 is 7.

Does sodium azide react with water?

When it is mixed with water or an acid, sodium azide changes rapidly to a toxic gas with a pungent (sharp) odor. It also changes into a toxic gas (hydrazoic acid) when it comes in contact with solid metals (for example, when it is poured into a drain pipe containing lead or copper).

How do you neutralize azide?

Solutions of 5% or less of sodium azide can be destroyed by reaction with freshly prepared nitrous acid. Destruction MUST be conducted in a working fume hood and in an open container due to the release of toxic nitric oxide (NO) gas.

How do you quench an azide?


  1. In a three-neck flask with a stirrer, dilute the azide with water so that it does not exceed 5%
  2. With stirring add a 20% solution of sodium nitrite containing 1.5 g of sodium nitrite per gram of azide.
