Ferroplasma Acidarmanus Produces Large Amounts of Sulfuric Acid Through

Question

Ferroplasma acidarmanus produces large amounts of sulfuric acid through A) oxidation of Cu⁺ with Cu(NO3)2. B) oxidation of FeS2with Fe3+ and H2O. C) oxidation of Fe3O2with Fe²⁺. D) oxidation of H2S with H2O. E) reduction of SO with H2.

Accepted Answer

Ferroplasma acidarmanus is known for its ability to oxidize iron sulfide minerals, such as FeS2, to produce sulfuric acid. This oxidation reaction involves the transfer of electrons from the sulfide mineral to an electron acceptor, such as Fe3+ or oxygen. The overall reaction can be represented as:

FeS2 + Fe3+ + H2O → 2 Fe2+ + 2 H+ + 2 SO4^2-

Therefore, choice B, which involves the oxidation of FeS with Fe3+ and HS0, is the most likely reaction that produces large amounts of sulfuric acid by Ferroplasma acidarmanus.
