Application

Water Purification Function
Sodium thiosulfate (hypo) can remove suspended solids and organic impurities from water through adsorption and precipitation, thereby increasing water clarity. Its adsorption capacity makes it widely used in aquaculture for water purification.

Buffering Agent
Due to its alkaline nature, sodium thiosulfate can act as a buffering agent to help maintain the pH balance of the dye bath. This ensures the consistency of the dyeing conditions and enhances the overall quality and uniformity of the dyed fabric.

Fixing agent
In photography and film processing, sodium thiosulfate is an important fixing agent that can dissolve unexposed silver halides, thereby completing the fixation of the image.

Leavening AgentIn
baked goods, sodium thiosulfate can react with acidic ingredients (such as vinegar or lemon juice) to produce carbon dioxide gas, which helps the dough expand. This makes it useful for making bread, biscuits, and other baked products. This function is similar to the use of baking soda (sodium bicarbonate) in baking.
