NINGBO INNO PHARMCHEM CO.,LTD. aims to equip professionals with a thorough understanding of key industrial chemicals, and Sodium Hydrosulfide Hydrate (CAS 207683-19-0) is a prime example. This compound, often referred to as sodium hydrosulfide hydrate, is a critical inorganic chemical with a wide range of applications, largely due to its sulfur-containing nature and its role as a source of hydrogen sulfide (H₂S).

Chemical Identity: The compound's CAS number is 207683-19-0. Its chemical formula is often represented as NaHS·xH₂O, indicating that it is a hydrate, meaning it contains a variable number of water molecules. A common form is NaHS·1.5H₂O. This hydration affects its physical properties and reactivity.

Key Properties: Sodium Hydrosulfide Hydrate typically appears as a white to light-yellow crystalline solid. It is highly soluble in water and possesses a distinct odor due to hydrolysis, which can release H₂S gas. Its basicity is notable, functioning similarly to sodium hydroxide in certain reactions. Its melting point is around 52-54°C.

Industrial Applications: As previously detailed, its industrial utility spans several sectors:

  • Mining: Acts as a flotation agent for mineral separation, particularly in copper ore processing.
  • Leather Tanning: Used as a dehairing agent to prepare animal hides.
  • Water Treatment: Effective in removing heavy metals and neutralizing chlorine.
  • Pulp & Paper: Essential in the kraft pulping process for efficient fiber extraction.
  • Textile Industry: Employed in dyeing processes to enhance fabric quality.
  • Chemical Synthesis: Serves as an intermediate for sulfur-containing organic compounds.

Comparison with Similar Compounds:

  • Sodium Sulfide (Na₂S): While both are sulfur compounds, Sodium Sulfide is a stronger base and has different solubility characteristics. NaHS is often preferred as a controlled H₂S donor in research.
  • Sodium Hydrosulfite (Na₂S₂O₄): This compound, also known as sodium dithionite, is a powerful reducing agent but structurally and functionally distinct from Sodium Hydrosulfide Hydrate. It is commonly used in textile bleaching and food preservation.
