Description

Nitrogen is a colorless, odorless, tasteless, non-toxic inert gas, slightly soluble in water, alcohol and ether. The chemical properties of nitrogen are not active, and it is very inert in its normal state. It is not easy to react with other substances. Nitrogen is not flammable. It combines with some particularly reactive metals, such as lithium and magnesium, to form nitrides. It also combines with hydrogen, oxygen and other elements at high temperatures. Slightly soluble in water and most other liquids, it is a poor conductor of heat and electricity.

Appearance:

Nitrogen appears as a colorless odorless gas. Noncombustible and nontoxic. Makes up the major portion of the atmosphere, but will not support life by itself. Used in food processing, in purging air conditioning and refrigeration systems, and in pressurizing aircraft tires. May cause asphyxiation by displacement of air. Under prolonged exposure to fire or heat containers may rupture violently and rocket.

Water Solubility:

slightly soluble H2O; insoluble alcohol [HAW93]

Storage Conditions:

Nitrogen is stable and chemically unreactive. It should be stored in tightly sealed metal cylinders in a cool, dry place.

Vapor Pressure:

-236 deg C at 1Pa (solid); -232 deg C at 10Pa (solid); -226.8 deg C at 100Pa (solid); -220.2 deg C at 1kPa (solid); -211.1 deg C at 10kPa (solid); -195.9 deg C at 100kPa (N2)

Vapor Density:

0.97 (vs air)

Flammability characteristics:

Non-flammable; non-toxic; suffocating

Explosive limit:

Liquid nitrogen is inherently safer than liquid oxygen or liquid air as a coolant, its ability to condense liquid oxygen out of the atmosphere can create hazards. A distillation tube containing a little solvent was cooled in liquid nitrogen while being sealed off in a blowpipe flame. A few minutes later the tube exploded, probably owing to a high internal pressure caused by evaporation of liquid oxygen which had condensed into the tube during sealing. It is possible that the atmosphere close to
