What is Sodium Thiosulphate Pentahydrate?

Sodium thiosulphate pentahydrate, also known as Sodium thiosulfate pentahydrate, is a chemical compound that consists of sodium (Na), sulfur (S), oxygen (O), and hydrogen (H) atoms. It is commonly referred to as “pentahydrate” because it contains five water molecules (H2O) bound to each sodium thiosulfate molecule. The chemical formula for sodium thiosulfate pentahydrate is Na2S2O3·5H2O. It is composed of two sodium ions (Na+), one thiosulfate ion (S2O32-), and five water molecules. The presence of water molecules in the compound is indicated by the “pentahydrate” part of its name.

Sodium thiosulfate pentahydrate is a white crystalline solid that is soluble in water. It is commonly used for various purposes, including photography, as a reducing agent, and in medical applications. In photography, it is used as a fixing agent to remove unexposed silver halide from photographic films or papers. In medical applications, it can be used as an antidote for cyanide poisoning. The presence of water molecules in the compound allows it to exist in a hydrated form, which can affect its physical and chemical properties. It is important to consider the specific form (anhydrous or hydrated) when using or handling sodium thiosulfate, as it may impact its stability, solubility, and reactivity.

Properties of Sodium Thiosulphate Pentahydrate

Sodium thiosulfate pentahydrate has several properties that are worth noting:

Physical Appearance

Sodium thiosulfate pentahydrate is a white crystalline solid, typically in the form of small crystals or powder. The individual crystals can be transparent or slightly translucent.


The “pentahydrate” designation indicates that each molecule of sodium thiosulfate is associated with five water molecules. This water content affects the stability and handling of the compound.


 It is highly soluble in water. Sodium thiosulfate pentahydrate readily dissolves and forms a clear, colourless solution. The solubility of sodium thiosulfate decreases as the temperature decreases.

Odor and Taste

Sodium thiosulfate pentahydrate is odorless and has a slight salty taste.


When dissolved in water, sodium thiosulfate pentahydrate solution is slightly alkaline, with a pH value around 9 to 10.


It is relatively stable under normal conditions. However, Sodium thiosulfate pentahydrate can slowly decompose over time, especially in the presence of moisture or high temperatures. Exposure to light can also degrade its stability.


Sodium thiosulfate pentahydrate is considered to be relatively safe to handle. It is not classified as a hazardous substance, but as with any chemical, proper precautions should be taken when handling or using it.

Sodium Thiosulphate Pentahydrate Applications

Sodium thiosulfate pentahydrate has a wide range of applications in various fields, including:

  1. Gold Mining: Sodium thiosulfate pentahydrate is used in gold mining as a leaching agent to extract gold from ores. It forms a complex with gold ions, facilitating their dissolution from the ore matrix.
  2. Water Treatment: It is employed in water treatment processes, particularly in dechlorination. Sodium thiosulfate pentahydrate effectively neutralizes chlorine compounds, which are commonly used for disinfection in water treatment, to eliminate their residual effects.
  3. Analytical Chemistry: Sodium thiosulfate pentahydrate serves as a reagent in analytical chemistry. It is used in titration methods to determine the concentration of certain compounds, such as iodine, by reacting with them in a redox reaction.
  4. Photography: It is crucial in the development of silver-based photographic film and prints. Sodium thiosulfate pentahydrate acts as a fixing agent by dissolving and removing unexposed silver halide, thus stabilizing the image and preventing further light sensitivity.
  5. Medicine: Sodium thiosulfate pentahydrate has medicinal applications. It is utilized as an antidote for cyanide poisoning, where it helps to detoxify cyanide by forming a non-toxic complex with it. Additionally, it is used in the treatment of certain skin conditions, such as pityriasis, to alleviate symptoms.
  6. Antidotes: It is employed as an antidote in general. Sodium thiosulfate pentahydrate acts as a counteractive agent, neutralizing the effects of various poisons or toxins in the body.

These diverse applications highlight the versatility and importance of sodium thiosulfate pentahydrate in different industries and fields.
