Stability: stability
It is rapidly decomposed into sodium hydroxide and sodium sulphide in damp air and exothermic. [3]
In the dry air, the heating turns yellow, the orange is changed, the melting is black, and the HCl produces H2S, and the reaction is intense. High moisture absorption, high moisture absorption and oxidation, hydrogen sulphide and sulfur are often released. [4]
Related reaction equation:
NaHS + HCl = = H2S + NaCl
NaHS heating + H2O = = H2S + NaOH
