Sodium Sulphide

Description : Scientific name: Sodium Sulphide

Sodium Sulphide is a reddish yellow substance that can be solved in water and alcohol and reacts with oxygen and is produced in liquid, flake and lump shape.

Sodium Sulphide is strongly combined with air and moisture and its molecules will be dissolved and this matter causes its Poor performance. It should be avoided as far as possible from reaching the air.

Sodium Sulphide is flammable and reacts with water, moisture and other chemical and metal substances. So, it should be kept in cool and dry place and away from direct sunlight and be kept in roofed warehouses.

The uses of Sodium Sulphide:

- Tanning, removing hair from skin

- Mining, separating stone from metal

- Paper industry, producing pulp

- Chemical industry, producing sulfur dyes

- Textile, reduction of sulfur dyes
