Product Description
Product Description of Sodium Sulfide CAS#1313-82-2
Sodium sulfide is a chemical compound with the formula Na₂S, and it is often encountered in its hydrated form Na₂S·9H₂O. Both forms are colorless, water-soluble salts that produce strongly alkaline solutions. When exposed to moisture in the air, Na₂S and its hydrates release hydrogen sulfide gas, which has a characteristic rotten egg odor. Anhydrous sodium sulfide appears as a yellow to brick-red crystalline solid or fused mass. Upon exposure to moisture, it can absorb water from the air, leading to spontaneous heating and potential ignition of nearby flammable materials. Industrial-grade sodium sulfide typically exhibits pink, reddish-brown, or yellowish-brown coloration due to the presence of impurities.
Product Application of Sodium Sulfide CAS#1313-82-2
Medical Research: Used in H₂S studies to investigate its effects on diabetes prevention in animal models.
Dye and Textile Industry: Functions in the production of sulfur dyes, as a reducing agent, and as a mordant.
Metallurgy and Mining: Employed in the oxidation of gold, lead, and copper ores and as a flotation agent.
Paper, Leather, and Rubber Processing: Used as a depilatory for leather, a digestion aid in paper-making, and in pigment and rubber treatments.

FAQ
Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.
Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.
Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.
Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
