Ammonia occurs in the atmospheres of the outer giant planets such as Jupiter (0.026% ammonia), Saturn (0.012% ammonia), and in the atmospheres and ices of Uranus and Neptune.

Sodium amide can be prepared by the reaction of sodium with ammonia gas, but it is usually prepared by the reaction in liquid ammonia using iron(III) nitrate as a catalyst.

- Sodium amide

Sodium amide is mainly used as a strong base in organic chemistry, often in liquid ammonia solution.

- Sodium amide

However, there are also other Brønsted bases which accept protons, such as aqueous solutions of ammonia (NH3) or its organic derivatives (amines).

- Base (chemistry)

Solvent properties: Ammonia readily dissolves in water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic. The maximum concentration of ammonia in water (a saturated solution) has a density of 0.880 g/cm3 and is often known as '.880 ammonia'.

- Ammonia

This occurs typically in compounds such as butyl lithium, alkoxides, and metal amides such as sodium amide.

- Base (chemistry)

When dry ammonia gas is heated with metallic sodium it converts to sodamide, NaNH2.
