Product Description

Product Description

Sodium thiosulfate pentahydrate (baking soda/Haibo) is a colorless and transparent crystal. It is a hydrate of sodium thiosulfate,
soluble in water, and the aqueous solution is weakly alkaline. It weathers in the dry air above 33 ° C and loses crystal water. It
is stable in neutral and alkaline solutions and will decompose rapidly in acidic solution.
