of the polythionic
acids and their corresponding salts, the polythionates. The
environmentally significant compounds. They are thought to form as intermediates in the chemical and
biochemical oxidation of reduced forms of sulfur to sulfate. This oxidation process, which also results in
acid production, is known to occur in aquatic systems draining mining and coal
Environmentally, the effects can be devastating. Addressing this problem will require a
thorough understanding of the relevant chemistry, and polythionate
chemistry is pivotal in that respect.
