Sodium thiosulfate, commonly known as "hypo," is a key component in photographic fixer solutions. In the development process, it removes unexposed silver halide crystals from photographic paper or film, preventing further image exposure and creating permanent prints.
Sodium thiosulfate used to dechlorinate water, neutralizing excess chlorine added to treat water sources. This is crucial as chlorine, while effective in disinfection, can harm aquatic ecosystems when discharged into water bodies. Sodium thiosulfate ensures that chlorinated water is safe for the environment after treatment.
Sodium thiosulfate is used as a fixing agent. It's employed to remove unexposed silver halide crystals from photographic films and papers. In textile printing, it helps fix dyes to the fabric, improving their wash and lightfastness.
Sodium thiosulfate is commonly used to dechlorinate water in the papermaking process. Chlorine and its compounds are often used for bleaching purposes in the pulp and paper industry. However, residual chlorine can have detrimental effects on the paper quality and can lead to yellowing and degradation over time. Sodium thiosulfate helps neutralize chlorine, preventing these negative effects and maintaining the paper's integrity and color.
