Photographic Anhydrous Sodium Thiosulfate

Photographic Anhydrous Sodium Thiosulfate, also known as hypo or sodium thiosulfate pentahydrate, is a chemical compound commonly used in the field of photography. It is classified under the supply class Photographic Supplies and belongs to the supply group Photographic Equipment.

Photographic Anhydrous Sodium Thiosulfate is primarily used as a fixing agent in the photographic development process. After an image is captured on a photosensitive material, such as film or photographic paper, it needs to be fixed to prevent further exposure to light. This fixing process removes any unexposed or undeveloped silver halide crystals from the material, making the image permanent and stable.

The chemical formula for Photographic Anhydrous Sodium Thiosulfate is Na2S2O3. It is available in the form of white crystalline powder or granules. When dissolved in water, it forms a clear solution.

In addition to its use in photography, Photographic Anhydrous Sodium Thiosulfate also finds applications in other industries. It is used in medical imaging, textile processing, and as a reducing agent in various chemical reactions.

When handling Photographic Anhydrous Sodium Thiosulfate, it is important to follow proper safety precautions. It should be stored in a cool, dry place away from incompatible substances. Protective equipment, such as gloves and goggles, should be worn when handling the chemical.

Overall, Photographic Anhydrous Sodium Thiosulfate is an essential component in the field of photography, playing a crucial role in the development and fixation of images.
