Sodium Hydrosulfide Hydrate - Premium Chemical Solution

Sodium hydrosulfide hydrate.Add 50 mL of absolute ether, immediately causing a large amount of white NaHS precipitate to form. Allow the mixture to stand, then add additional ether in several portions until no further white precipitate appears in the supernatant. A total of approximately 110 mL of ether is typically required.

Quickly filter the precipitate, wash it 2–3 times with absolute ether, and suction-dry it before transferring to a vacuum desiccator. The resulting product achieves analytical-grade purity. For higher-purity sodium hydrosulfide hydrate, the product can be dissolved in ethanol and recrystallized by adding ether.
