Ammonium thiosulfate is widely used in photography as a fixing agent to dissolve unexposed silver halides from photographic films and papers, ensuring image stability. In agriculture, it serves as a liquid fertilizer, providing a readily available source of sulfur and nitrogen to crops, enhancing growth and yield. It is also employed in mining for gold and silver extraction, where it acts as a non-toxic alternative to cyanide in leaching processes. Additionally, it finds use in water treatment to remove chlorine and in the textile industry as a bleaching agent for fabrics. Its versatility makes it valuable across multiple industries.
