Sodium dithionite is stable when dry, but aqueous solutions deteriorate due to the following reaction: 2 S 2 O 4 2− + H 2 O → S 2 O 3 2− + 2 HSO 3 − This behavior is consistent with the instability of dithionous acid. Thus, solutions of sodium dithionite cannot be stored for a long period of time.
Sodium hydrosulfide hydrate is a hydrated inorganic salt of sodium. It participates in the synthesis of (E)2cyano2(thiazolidin2ylidene)ethanethioamide. Application It may be used as a sulfur nucleophile to induce the CS bond formation in α,βdichloro vinyl ketones to form 5 to 8membered cyclic thioethers.

Sodium Hydrosulfide. Sodium hydrosulfide is used more as a common commercial form than sodium sulfide. It is prepared by absorption of hydrogen sulfide in sodium hydroxide. It is shipped as a 45% solution with a specific gravity of and a pH of The viscosity is 7 centipoise. The solution tends to crystallize below 62°F (17°C).

Patch clamp studies of neuroblastoma cells have shown that in the presence of sodium hydrogen sulfide, the in vitro precursor of hydrogen sulfide, addition of the sulfonated amino acids, taurine or cysteic acid resulted in reversible abolition of the inward of the sodium currents. This effect could also be demonstrated by preincubating cells for 320 min within 510 mM sodium hydrosulfide ...

Sodium Hydrosulphide (NS) flakes, liquid, solid. Mining: Flotation agent. NS is also used as a substitute for sodium sulphide for the sulphidization of copper, oxides of copper, lead or zinc making them amenable to collector attack. Commonly used prior to collector addition for the activation of Cu, Pb, and Zn minerals.
