Brief Introduction:
Sodium thiosulfate (Na₂S₂O₃), a versatile inorganic compound, demonstrates significant applications across diverse scientific disciplines, as evidenced by recent research. In agricultural studies, it has been utilized in combination with silver nitrate as a foliar spray to enhance cucumber (Cucumis sativus L.) trichome density and morphology, with transcriptomic analyses revealing upregulation of stress-responsive and trichome-associated genes, suggesting potential roles in plant defense mechanisms. In metallurgical contexts, sodium thiosulfate serves as a critical component in alkaline leaching systems for gold extraction from auriferous ores, achieving high recovery rates (89.3% within 6 hours) when paired with glycine and copper ions, thereby offering an environmentally favorable alternative to cyanidation. Clinically, it has emerged as an effective therapeutic agent for managing calciphylaxis in end-stage renal disease patients, with intravenous administration demonstrating notable improvement in refractory ulcer healing without adverse effects.
Inorganic Compounds
As a salt of thiosulfuric acid, sodium thiosulfate is clearly an inorganic compound.
Thiosulfates
Sodium Thiosulfate, Na₂S₂O₃, is the most common and widely used thiosulfate salt.
Reducing Agents
Sodium thiosulfate acts as a mild reducing agent, especially in redox reactions (e.g., with iodine).
Photographic Chemicals
In photography, it is used as a fixer (also known as "hypo") to dissolve undeveloped silver halide crystals.
