The simple reaction is: 2Na + S----------Na2S (in same conditions: ammonia solution or tetrahydrofuran)
Why would it preserve anything? Sodium sulphide is unstable in the presence of water and forms hydrogen sulphide gas - which is highly toxic and is the smell of bad eggs,
by using sodium dithionite or hydrogen sulphide
Iron and sulphur make iron sulphide
Na2S + 2HCl = 2NaCl + H2S (smelly toxic gas) Sodium sulphide + hydrochloric acid => Salt (Sodium chloride) and Hydrogen sulphide
Sodium nitroprusside is used for detection of sulphur in organic compounds. If sulphur is present in the organic compound, sodium fusion will convert it into sodium sulphide. Sulphide ions are readily identified using sodium nitroprusside. Na + S = Na2S Na2s + Na2[Fe(CN)5NO] = Na4[Fe(CN)5NOS] Sodium nitroprusside violet colour Submitted by Dr Arun Trikha on July 22nd 2012 .
Sodium sulphide has one sodium atom and two sulphur atoms. NA2S
Sodium, Sulfur
Na(2)S
Na + 2S --> Na2S Sodium and Sulphur yield Sodium Sulphide.

Iron Sulphide
