Descrizione

Descrizione generale

Sodium thiosulfate (Na₂S₂O₃) can be obtained from Na₂S₂O₃.10H₂O by heating above 100 °C. It can be synthesized from sodium sulfate.

Applicazioni

Applied in a widely useful, thiosulfate-assisted, synthesis of a variety of diamine-CuCN complexes.

Sodium thiosulfate (Na₂S₂O₃) may be used in the following studies:

• Industrial synthesis of methylene blue.
• Quantitative estimation of elemental iodine by titrimetry.
• Detection of trace levels of cysteine by employing triangular silver nanoplates (TAg-NPs).

Redi-Dri^™ is an innovative packaging product line that helps eliminate clumping material by adding extra packaging process steps without any chemical additives, anti-clumping agents, or hydrophobic compounds. Redi Dri offers a more convenient and safer way to handle the products.
