Main Characteristic of Sodium Thiosulphate:
1.colorless and transparent crystal.
2.It is a hydrate of sodium thiosulfate, soluble in water, and the aqueous solution is weakly alkaline.
3. It weathers in the dry air above 33 ° C and loses crystal water.
4. It is stable in neutral and alkaline solutions and will decompose rapidly in acidic solution.
