  • Usage
  • Sodium thio sulfate is also used: As a component in hand warmers and other chemical heating pads that produce heat by exothermic crystallization of a supercooled solution. In bacteriological water assessment, as it promotes the survival of coliform organisms by neutralizing residual chlorine.[15]:249[16]:572 In the tanning of leather To demonstrate the concept of super cooling in physics classes: Sodium thio sulfate, when heated, dissolves in its own water of crystallization. This solution can be cooled to room temperature without re crystallization. When crystallization is induced by the addition of a small seed crystal, the sudden temperature rise can be experienced by touch. As part of patina recipes for copper alloys Often used in pharmaceutical preparations as an anionic surfactant to aid in dispersion
