Q: How should ammonium thiosulphate 95% extra pure be stored to ensure maximum shelf life?
A: Store the compound in a cool, dry place, away from heat and moisture. Keep it tightly sealed in its original plastic bottle, and avoid proximity to acids and oxidizing agents to prevent decomposition and maintain a shelf life of up to 3 years.
Q: What are the main uses of ammonium thiosulphate in laboratories and industry?
A: It is commonly used as a reducing agent, photographic fixing agent, and analytical reagent. Its stable nature and reliable solubility make it essential for experiments, photographic processing, and certain industrial processes.
Q: When handling ammonium thiosulphate, are there any hazards or precautions I should be aware of?
A: Ammonium thiosulphate is classified as an irritant. Always wear appropriate protective equipment, such as gloves and safety goggles, and avoid inhaling dust or vapors. Ensure adequate ventilation and avoid contact with acids, which can release sulfur dioxide gas.
Q: Where can ammonium thiosulphate 95% extra pure be purchased or supplied in India?
A: This product is available through chemical distributors, importers, manufacturers, and suppliers across India. It is typically provided in 500-gram plastic bottles, suitable for laboratory and industrial applications.
Q: What is the typical process for using ammonium thiosulphate as a photographic fixing agent?
A: In photographic processing, the compound is dissolved in water to prepare a fixer solution. It interacts with unreacted silver halides on the film or print, converting them into soluble silver thiosulphate complexes, which are then washed away, resulting in a stable, fixed image.
Q: What benefits does ammonium thiosulphate offer compared to other fixing agents?
A: Its high solubility, purity, and mild sulfur odor make it user-friendly and effective for precise results. Additionally, its chemical stability and non-flammable nature enhance safety and reliability in laboratory and industrial uses.
