Sodium thiosulfate formation
Thread Content
Is it possible to produce sodium thiosulfate by passing hydrogen sulfide gas into a sodium carbonate solution? If so, under what conditions?
What is the required alkaline range for sodium carbonate when producing sodium thiosulfate? Are there any requirements for temperature as well?

May I ask that raising the pH value will increase the reaction rate of sodium thiosulfate, thereby increasing the amount of sodium thiosulfate produced. I wonder how the pH value affects its reaction?
