väävlipõhine

väävlipõhine describes substances or processes that involve sulfur as a primary component or reactant. In chemistry, sulfur is a non-metal element with the symbol S and atomic number 16. It exists in various allotropes and forms numerous compounds. Many industrial processes and naturally occurring phenomena rely on sulfur or its derivatives.

For instance, sulfuric acid (H2SO4) is a widely produced industrial chemical that is sulfur-based. It is crucial in fertilizer production, petroleum refining, and wastewater treatment. Other sulfur-based compounds include hydrogen sulfide (H2S), a gas often associated with the smell of rotten eggs, and sulfur dioxide (SO2), a gas produced by burning fossil fuels and volcanic activity, which can contribute to acid rain.

In materials science, vulcanization is a process that uses sulfur to improve the strength and elasticity of rubber, making it a sulfur-based treatment. Organic chemistry also features many sulfur-containing functional groups, such as thiols and sulfides, which play roles in biological molecules like proteins and in the synthesis of pharmaceuticals and other chemicals. The term "väävlipõhine" is therefore a broad descriptor encompassing a wide range of chemical and material applications and occurrences.
