Application

 

Photography:
In the photography industry, it is used as a fixer. It helps to dissolve the unexposed silver halides on the photographic film or paper, making the image permanent.

Water Treatment:
It can be used to remove chlorin e from water. Sodium thiosulfide reacts with chlorin e, converting it into chloride ions, which are less harmful to the environment and to organisms.

Gold Mining:
In some gold - mining processes, it is used to extract gold from ores. It forms a complex with gold, which can then be separated from the other minerals.

Chemical Analysis:
It is used in iodometric titrations. In these titrations, sodium thiosulfide is used to quantitatively determine the amount of iodine or other oxidizing agents in a sample.
