rikkivety
Rikkivety, the Finnish term for hydrogen sulfide (H2S), designates a colorless, flammable gas with the characteristic odor of rotten eggs at low concentrations. H2S is a weak diprotic acid that dissolves in water to form hydrosulfide (HS-) and sulfide (S2-). Its standard boiling point is −60.7 °C, so it is a gas at room temperature, and it is notably denser than air, which can lead to accumulation in poorly ventilated spaces.
Occurrence and production: H2S occurs in nature in volcanic gases, hot springs, and flatulent organic matter;
Industrial relevance: Industrially, H2S is primarily encountered as an intermediate in sulfur recovery processes, notably the
Safety and handling: H2S is highly toxic and poses serious health risks upon inhalation, causing irritation,
Name and language note: rikkivety is the Finnish name; in English, the compound is hydrogen sulfide (H2S).
