General description

Sodium thiosulfate solution is widely used in titration, particularly in iodometric and redox titrations. It serves as a standard reducing agent to determine the concentration of oxidizing agents such as iodine, chlorine, and hydrogen peroxide.

Application

Sodium thiosulfate solution can be utilized in the preparation of volumetric solutions through dilution. The resulting diluted solution is employed in redox titrations to determine the concentration of hydrogen sulfide in rural biogas.
