(Na2S2O3) or Sodium thiosulfate, or thio sulphate is a colorless crystalline compound that is more familiar as the pentahydrate, Na2S2O3•5H2O.  It is an efflorescent, monoclinic crystalline substance also called sodium hyposulfite or “hypo.”

Medical Use
It is used as an antidote to cyanide poisoning. Thiosulphate acts as a sulfur donor for the conversion for cyanide to thiocyanate (which can then be safely excreted in the urine), catalyzed by the enzyme rhodanase.
It has also been used as treatment of calciphylaxis in hem dialysis patients with end-stage renal disease.

Other uses
Sodium thiosulfate is used as a component in hand warmers and other chemical heating pads that produce heat by exothermic crystallization of a super cooled solution.
Hypo is used in Bleach
In pH testing of bleach substances.
To de-chlorinate tap water for aquariums or treat effluent from waste water treatments prior to release into rivers. The amount of Sodium thiosulphate required can vary with the pH of the water.  A range of approximately 2 to 7 parts sodium thiosulfate to neutralize one part chlorine is generally suggested. To neutralize 1 liter of a 200 ppm chlorine solution, approximately 0.4 - 1.4 grams of sodium thiosulfate would be required. 
It is used to remove iodine stains, e.g. after the explosion of nitrogen triiodide.
It is used in bacteriological water assessment.
It is used in the tanning of leather.
It is used in phase change material.
Sodium thiosulfate is used in paper industry.
It is used in medicine and as disinfectant. It is systemically for cyanide or arsenic poisoning and topically as an anti­fungal.
It is used in electroplating.
As part of patina recipes for copper alloys.
Often used in pharmaceutical preparations as an anionic surfactant to aid in dispersion.

Zinc Chloride Information


Dry Cell  or Batteries: Zinc chloride is commonly used in dry cell batteries as an electrolyte where it also acts as a moisture absorbent and corrosion inhibitor. It is an excellent water soluble Zinc source for uses compatible with chlorides. Chloride compounds can conduct electricity when fused or dissolved in water.
: Today, there are three primary types of acid zinc plating baths: straight ammonium chloride, straight potassium chloride and mixed ammonium chloride/potassium chloride. Acid zinc plating systems have several advantages over alkaline cyanide and alkaline non-cyanide zinc plating systems except that in acid zinc plating, the electrolyte is extremely corrosive.
Ammonium chloride zinc plating
. The ammonium chloride bath is the most forgiving of the three major types of acid zinc plating because of its wide operating parameters.
Potassium chloride zinc plating. Potassium chloride zinc plating solutions are attractive because they contain no ammonia. The disadvantages of this system are a greater tendency to burn on extreme edges and higher operating costs.
Mixed ammonium chloride/potassium chloride zinc plating. This bath combines the best of the ammonia and ammonia-free baths. Because potassium chloride is less expensive than ammonium chloride, the maintenance costs of the mixed bath are lower than the ammonia bath.
Galvanizing, Soldering and Tinning Fluxes:  Zinc chloride is used in fluxes for galvanizing, soldering and tinning. Its ability to remove oxides and salts from metal surfaces insures good metal to metal bonding. It has the ability to attack metal oxides (MO) to give derivatives of the formula MZnOCl2. This reaction is relevant to the utility of Zinc chloride as a flux for soldering - it dissolves oxide coatings exposing the clean metal surface. Typically this flux was prepared by dissolving zinc foil in dilute hydrochloric acid until the liquid ceased to evolve hydrogen; for this reason, such flux was once known as killed spirits or "Marela".
Agriculture: Zinc chloride is very rarely used in agriculture. It may be reacted with chelating agents to form solutions of zinc that are biologically available to plants and animals. It's the Chelate manufacturing that consumes Zinc chloride.
Petroleum: It is an excellent emulsion breaker and is used to separate oil from water. It is also an effective packer fluid in oil and gas wells due to its high specific gravity. However its a little more costly than the other low specific gravity fluids used in the process.
Water Treatment: It is used in specialty corrosion inhibitors in cooling towers, potable water, and in gas and oil wells.
Resins: It is used in Ion - Exchange resins production.
Paints: It is used in for the production of lithopone and as pigment for zinc chromate.
Rubber: It is used as accelerator in the vulcanizing process of rubber.
Glue, wood working: Zinc chloride is used in for the preservation of glue, and for the impregnation of timber.
Printing: It is used in off-set in the chemical products.
Odor Control: It reacts with sulfide to minimize release of H2S gas in waste treatment facilities.
Oil-Gas Wells: High-density solutions of Zinc Chloride and calcium chloride give good performance in well completion and work-over operations; the solutions also used as packer fluids under certain well conditions. ZnCl2 has been used in specialty corrosion inhibitors and invert emulsion breakers.
Vulcanized Fiber & Reclaimed Rubber: Water-leaf paper is gelatinized with zinc chloride solution is less tacky, drier and less moisture-absorbent than caustic reclaimed rubber.
Animal drug: It is used for the production of zinc bacitracin.
Herbicide: Zinc chloride is used as an herbicide. It is used to control lichen and moss growing on the roofs of houses and other domestic dwellings, along walks, driveways, fences, and wherever moss grows.
Chemical: Zinc Chloride is used in the production of ethyl acetate. It is used as condensing agent for the production of organic dye-stuff. It is used as a stabilizing agent for diazonium compounds. It is used for the production of active carbon. Zinc Chloride Anhydrous  is used for Friedel Craft Reaction, Azotropic or Azeotropic Distillation, Desiccation etc.
Miscellaneous: ...and many more.
