Chemical Formula of Sodium Hydrosulfide: NaHS
Sodium Hydrosulfide consists of sodium ions (Na⁺) and hydrosulfide ions (HS⁻), which provide strong sulfidizing properties when dissolved in water.This chemical property makes NaHS extremely effective in mineral flotation processes and heavy metal precipitation reactions.
Sodium Hydrosulfide is an inorganic sulfur compound widely used in industrial processes requiring sulfurization, reduction, or metal sulfide formation. It is particularly important in mineral processing and metallurgical applications because of its ability to convert metal oxides into metal sulfides.
It serves as an important sulfidizing agent, depressant, and sulfur source in various chemical and metallurgical industries.Our Sodium Hydrosulfide 70% flakes are produced under strict quality control standards to ensure high purity, stable chemical composition, and excellent solubility, making them suitable for demanding industrial applications.
As a professional Sodium Hydrosulfide supplier and exporter, we provide reliable product quality, competitive pricing, and global logistics support for mining companies, chemical distributors, and industrial manufacturers worldwide.
