Sodium Sulfide Nonahydrate Sds

Sodium sulfide nonahydrate SDS is a compound with the chemical formula Na2S·9H2O. It is a white to yellowish crystalline solid that is highly soluble in water. The compound is commonly used in the chemical industry as a reducing agent and as a source of sulfur for the production of other chemicals.

The structure of sodium sulfide nonahydrate consists of Na+ cations and S2- anions, which are arranged in a cubic crystal lattice. Each Na+ ion is surrounded by six S2- ions, and each S2- ion is coordinated to six Na+ ions. The nine water molecules in the compound are attached to the sodium cations through hydrogen bonding.

When sodium sulfide nonahydrate is heated, it decomposes to form sodium sulfide heptahydrate (Na2S·7H2O), which in turn decomposes further to form sodium sulfide anhydrous (Na2S). This reaction releases water and sulfur dioxide gas.

Sodium sulfide nonahydrate is a strong reducing agent and can react violently with oxidizing agents. It can also be corrosive to metals and may cause severe burns and eye damage upon contact with skin or eyes. Therefore, appropriate safety measures should be taken when handling this compound.
