What is the ethanol potassium hydroxide solution of sodium sulfide adding carbon tetracloride to produce red precipitation?
Red precipitation may be sodium polysulfide precipitation.Sodium sulfide is more likely to be oxidized by air to sodium polysulfide (make sulfur into single matter, and then produce sodium polysulfide). When the sulfur index of sodium polysulfide is high, it is dark red in the aqueous solution, a...Read more -

Sodium Hydrosulfide Production
1. Absorption method: Absorb hydrogen sulfide gas with alkali sulfide solution (or caustic soda solution). Because hydrogen sulfide gas is toxic, the absorption reaction should be carried out under negative pressure. In order to prevent the high pollution of the air by hydrogen sulfide in the exh...Read more -
