Yes, sodium thiosulfate can be a reactant in chemical reactions, such as in photography as a fixing agent or in medical treatments for cyanide poisoning. It can also be used in measuring the concentration of other substances through titration reactions.

Polonium is not used in photography.
Copper thiosulfate is the chemical name for Cu2S2O3. It is commonly used as a complexing agent in chemical solutions and photography.
Photographic fixing agent. An emulsion of sodium thiosulfate (called hypo by photographers) is used to stop development of exposed film. Thiosulfate converts undeveloped silver bromide grains in the film into water-soluble silver thiosulfate complexes that can be removed when the film is washed.S2O32- + AgBr(s) AgS2O3- + Br-S2O32- + AgS2O3- Ag(S2O3)23-Thiosulfate is also an antidote for cyanide poisoning. It reacts with cyanide to produce sulfite and thiocyanate ions:CN- + S2O32- SCN- + SO32-This reaction is catalyzed by an enzyme produced by cell mitochondria to neutralize small quantities of ingested cyanide (which occurs naturally in cassava root, lima beans, and almonds!).
Sodium thiosulfate is neither an acid nor a base; it is a salt composed of sodium cations and thiosulfate anions. It is often used in photography as a fixing agent to dissolve unexposed silver halide in film or prints.

Some common photography lighting styles used in professional photography include natural light, studio lighting, and flash photography. Each style has its own unique characteristics and can be used to create different effects in photographs.
The idea of permanently capturing an image on a substrate was thought of by Thomas Wedgwood in England, but his early attempts used silver nitrate without a fixing agent, meaning the images could not leave darkened rooms. The first known photograph taken by a camera is credited to French inventor Joseph Nicéphore Niépce, who in 1826 successfully captured a permanent image using a camera obscura.
It is widely used in standard film-based (pre-digital) Photography.
