Its capacity to neutralize chlorine, aid in chemical heating, and serve as an anionic surfactant makes it a valuable component for manufacturers and laboratories.
Physical and Chemical Characteristics
This compound appears as a white, odorless crystal with a molecular weight of 158.11 g/mol. It melts at 48.3C and boasts high water solubility: 70.1 g/100 mL at 20C and 231 g/100 mL at 100C. Its density is 1.667 g/cm3 and it has a neutral to mildly alkaline pH range between 6.5 and 8.
Safe Handling and Storage
Sodium Thiosulphate Pentahydrate is non-poisonous and should be stored at room temperature away from moisture and direct sunlight. Its four-year shelf life makes it convenient for both bulk storage and regular usage in industrial or laboratory settings.
FAQ's of Sodium Thiosulphate Pentahydrate:
Q: How should Sodium Thiosulphate Pentahydrate be stored for maximum shelf life?
A: It should be stored at room temperature in a tightly sealed container, away from moisture and direct sunlight, to ensure its stability and maintain its shelf life of up to four years.Q: What are the primary industrial uses of Sodium Thiosulphate Pentahydrate?
A: This compound is primarily utilized in water treatment (neutralizing residual chlorine), leather tanning, heat packs, patina applications for copper alloys, and as a surfactant in pharmaceuticals. It's also used for supercooling demonstrations in education.Q: When is Sodium Thiosulphate Pentahydrate used in bacteriological water assessment?
A: It is used during water testing to neutralize any remaining chlorine, which helps preserve coliform bacteria, ensuring accurate assessment of microbial content in water samples.Q: How does Sodium Thiosulphate Pentahydrate demonstrate the concept of supercooling?
A: When heated, it dissolves in its own crystallization water. The solution can then be cooled to room temperature without crystallizing; the addition of a small seed crystal instantly triggers crystallization, releasing heat and serving as a practical demonstration of supercooling.Q: What physical characteristics distinguish Sodium Thiosulphate Pentahydrate?
A: It appears as white, odorless crystals, has a molecular weight of 158.11 g/mol, a melting point of 48.3C, is highly soluble in water, and has a slightly alkaline pH of 6.5-8.Q: Is Sodium Thiosulphate Pentahydrate safe to handle and use?
A: Yes, it is considered non-poisonous and safe for industrial and laboratory applications when standard chemical handling procedures are followed.Q: Where can Sodium Thiosulphate Pentahydrate be sourced?
A: It is available from chemical distributors, exporters, importers, manufacturers, and suppliers globally, including in India. Check local chemical supply companies for specific sourcing information.Tell us about your requirement
