Sodium sulfide appears as white or light yellow crystalline granules at room temperature, emitting a smell similar to rotten eggs. While it may feel like ordinary salt grains, it should never be handled directly with bare hands. Upon contact with water, it becomes slippery and can cause skin irritation. Two forms are commonly available in the market: anhydrous sodium sulfide, which resembles small rock candy pieces, and nonahydrate sodium sulfide, which looks more like translucent jelly-like chunks.
