Pnictogen hydrides or hydrogen pnictides are binary compounds of hydrogen with pnictogen ( or ; from Unlike other hydrides such as hydrogen sulfide and hydrogen fluoride, which form acidic aqueous solutions, ammonia dissolves in water to make ammonium hydroxide which is basic (by forming a hydroxide ion as opposed to hydronium). Phosphine is also water-soluble. Arsine and stibine are less so, and it is not known if bismuthine is.

Hydride

In chemistry, a hydride is formally the anion of hydrogen (H). The term is applied loosely. At one extreme, all compounds containing covalently bound H atoms are called hydrides: water (H2O) is a hydride of oxygen, ammonia is a hydride of nitrogen, etc. For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached to a less electronegative element. In such cases, the H centre has nucleophilic character, which contrasts with the protic character of acids. The hydride anion is very rarely observed.

Almost all of the elements form binary compounds with hydrogen, the exceptions being He, Ne, Ar, Kr, Pm, Os, Ir, Rn, Fr, and Ra. Exotic molecules such as positronium hydride have also been made.
