What is Sodium Thiosulphate Crystal?

Sodium thiosulfate crystal is a chemical compound with the formula Na2S2O3. It is also known by other names such as sodium thiosulphate or sodium hyposulfite. It is a colourless, crystalline solid that is highly soluble in water. It is commonly used in various applications, including photography, medicine, and as a laboratory reagent. One of sodium thiosulfate crystal’s well-known uses is as a fixing agent in photography. In the development process of traditional film photography, sodium thiosulfate is used to remove unexposed silver halide from the photographic film, thereby fixing the image and preventing further exposure to light.

Furthermore, it has medical applications and is sometimes used as an antidote to cyanide poisoning. Sodium thiosulfate crystal works by reacting with cyanide to form a less toxic compound, which can be eliminated from the body more easily. In the laboratory, it is utilized as a reducing agent and a titrant in various chemical reactions. Sodium thiosulfate crystal can also be employed to neutralize excess chlorine or iodine in water treatment processes.

Overall, sodium thiosulfate crystal is a versatile compound with several practical applications in photography, medicine, and chemistry.

Properties of Sodium Thiosulphate Crystal

Sodium thiosulphate crystals possess several properties that make them useful in various applications. Here are some key properties of sodium thiosulfate crystals:

Physical State

Sodium thiosulphate crystals are typically found as colourless, transparent, or white solid crystals. They have a crystalline structure.


Sodium thiosulfate is highly soluble in water. It readily dissolves in water, forming a clear, colourless solution. The solubility of sodium thiosulfate increases with higher temperatures.


Sodium thiosulphate crystals are odorless.


The density of sodium thiosulfate crystals is approximately 1.67 grams per cubic centimetre (g/cm³).

Melting Point

It has a relatively high melting point of around 48.3 degrees Celsius (119 degrees Fahrenheit). At this temperature, the solid crystals convert into a liquid form.

Chemical Formula

The chemical formula of Sodium thiosulphate crystal is Na2S2O3. It indicates that each sodium thiosulfate molecule consists of two sodium (Na) atoms, two sulfur (S) atoms, and three oxygen (O) atoms.

Reducing Agent

Sodium thiosulphate can act as a reducing agent in chemical reactions. It can donate electrons to other substances, thereby reducing their oxidation state.


Sodium thiosulfate crystals are relatively stable under normal conditions. They do not decompose easily and have a long shelf life when stored properly.


A solution of Sodium thiosulphate crystal has a pH level around 7, making it close to neutral.

Sodium Thiosulphate Crystal Applications

Sodium thiosulphate crystals have several applications in various fields due to their unique properties. Here are some common applications:

  1. Photography: Sodium thiosulfate is widely used in the field of photography as a fixing agent. It is used to remove unexposed silver halide from photographic film or paper during the development process. This helps to fix the image and prevent further exposure to light.
  2. Medical Uses: It has medical applications as well. Sodium thiosulphate is used as an antidote for cyanide poisoning. When administered intravenously, sodium thiosulphate reacts with cyanide to form thiocyanate, which is less toxic and can be eliminated from the body more easily.
  3. Water Treatment: Sodium thiosulphate is utilized in water treatment processes to neutralize excess chlorine or iodine. It helps in removing these disinfectants from water, making it safe for various applications.
  4. Analytical Chemistry: It is employed as a titrant and reducing agent in analytical chemistry. Sodium thiosulphate is used in redox reactions, particularly in iodometry, to determine the concentration of oxidizing agents like iodine.
  5. Gold and Silver Extraction: Sodium thiosulphate is used in the extraction of gold and silver from ores. It forms complexes with these metals, making it easier to dissolve and extract them from their respective ores.
  6. Cosmetic Industry: Sodium thiosulphate is used in cosmetic products, particularly in hair care. It is added to hair color removers to help break down and remove hair dye from the hair shaft.
  7. Aquariums: It is used in aquariums to remove chlorine and detoxify water during water changes or when introducing new fish. Sodium thiosulphate helps in ensuring a safe environment for aquatic organisms.
  8. Industrial Applications: Sodium thiosulphate finds applications in various industrial processes. It is used in textile and paper industries as a bleaching agent and dechlorinating agent. It is also used in the extraction of certain metals from their ores.

These are just a few examples of the many applications of sodium thiosulphate crystals. Its versatile properties make it valuable in multiple industries and scientific fields.
