Sodium Sulfide Nonahydrate Sigma

Sodium sulfide nonahydrate sigma is a white crystalline solid with the chemical formula Na2S∙9H2O. It is also known as sodium sulfide enneahydrate or sodium sulfide nona. The compound is highly soluble in water and has a strong odor of hydrogen sulfide.

In terms of its chemical composition, sodium sulfide nonahydrate contains two sodium ions (Na+) and one sulfide ion (S2-) for every formula unit. The nine water molecules in the crystal structure are held in place by hydrogen bonds with the sulfide and sodium ions.

Sodium sulfide nonahydrate is commonly used in a variety of industrial applications such as ore flotation, leather tanning, and the production of sulfur dyes. It is also used as a reducing agent in organic chemistry reactions.

It is important to handle sodium sulfide nonahydrate with caution as it can be corrosive to skin and eyes. Protective equipment such as gloves and goggles should be worn when handling the compound. Additionally, it should be stored in a cool, dry place away from incompatible materials such as acids and oxidizers.
