What is Sodium sulfide?
Sodium sulfide (also known as Sodium sulfuret and sodium monosulphide) is a yellow solid flake with a sulfurous smell. It is a sulfide salt, which creates a strong alkaline solution when dissolved in water and can cause chemical burns. Sodium sulfide can react with acids to produce hydrogen sulfide, which is highly toxic.
Sodium sulfide is a toxic and corrosive substance that causes severe skin burns and mucous membrane.

Sodium sulfide production
Sodium sulfide (Na2S) is produced industrially by:
Na2SO4 + 2 C → Na2S + 2 CO2
In the laboratory, Na2S can be produced by the reduction of sulfur with sodium in anhydrous ammonia with a catalytic amount of naphthalene.
2 Na + S → Na2S
