Frequently asked questions
What is ammonium polysulfide solution primarily used for?
Ammonium polysulfide solution is commonly used as an analytical reagent in qualitative inorganic analysis to dissolve and separate the sulfides of arsenic, antimony and tin, as well as for metal surface treatment, leather processing, and rubber reclaiming due to its strong reducing and sulfur-donating properties.
What is the chemical formula and molecular weight of ammonium polysulfide?
The general formula is (NH₄)₂Sₓ, where x varies (typically 2–6). The exact molecular weight (MW) depends on the sulfur chain length, but it ranges roughly between 108–250 g/mol for common compositions.
How should ammonium polysulfide solution be stored?
Store in a cool, dry, well-ventilated area at ambient temperature, away from oxidizing agents, acids, and incompatible materials. Keep containers tightly sealed to prevent exposure to moisture or air.
What grades or purity levels of ammonium polysulfide solution does Molekula supply?
Molekula supplies technical-grade ammonium polysulfide solution (22% min w/w active sulfur). This grade is optimized for industrial applications and meets standard specifications for sulfur content and impurities.
Can Molekula supply ammonium polysulfide solution in bulk quantities?
Yes, Molekula can provide bulk quantities (e.g., IBC totes, drums, or tanker loads) depending on order volume and logistics. Contact our sales team for custom packaging and delivery options.
What documentation is included with an order of ammonium polysulfide solution?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS/SDS), and batch-specific documentation (e.g., test reports for sulfur content and impurities). Additional certifications (e.g., REACH, FDA compliance) may be provided upon request.
