Sodium Hydrosulfide is an inorganic compound with the formula NaHS. It is colorless needle-like crystal and easily deliquesced. It is soluble in water and alcohols. Crystalline NaHS exists in two phase transitions. At temperatures above 360 K, NaHS assumes the NaCl structure, which implies that the HS− behaves as a spherical anion due to its rapid rotation leading to equal occupancy of eight equivalent positions. Below 360 K, a rhombohedral structure forms, and the HS− sweeps out a discoidal shape. Below 114 K, the structure becomes monoclinic.
It is produced by the reaction of sodium hydroxide and hydrogen sulfide.
NaOH + H2S → NaHS + H2O
