What is the primary characteristic of hydrogen sulfide?

The primary characteristic of hydrogen sulfide is that it has the odor of rotten eggs and is corrosive. Hydrogen sulfide is a colorless gas that is well-known for its distinct and unpleasant smell, which is often compared to that of rotten eggs. This characteristic makes it easily recognizable in low concentrations, allowing individuals to detect its presence.

Additionally, hydrogen sulfide is indeed corrosive; it can damage various materials and surfaces, including metals and certain building materials. This property poses significant risks in environments where hydrogen sulfide is present, such as in natural gas production and sewage treatment facilities. Understanding both the odor and corrosive nature of hydrogen sulfide is crucial for safety and response protocols in scenarios where this gas might be encountered.
