Potassium thiosulfate (Cat No.:M060753）is a water-soluble inorganic salt composed of potassium cations and thiosulfate anions. It typically appears as a white crystalline solid and is widely used in photography, agriculture, and analytical chemistry. In agriculture, it serves as a liquid fertilizer providing both potassium and sulfur, promoting crop growth and nutrient uptake. In photographic processing, it acts as a fixer, dissolving unreacted silver halides from film. Potassium thiosulfate is also employed as a reducing agent and in gold leaching solutions for environmentally friendly mining practices. It is non-toxic and stable under normal conditions.
