Sulfuric acid is a very strong acid that can act as an oxidizing agent at high concentrations (very low pH, or even negative pH values). Under standard conditions, sulfuric acid has a low reduction potential, SO42−(aq)+4H+(aq)+2e−⇌SO2(g)+2H2O(l), +0.20 V which means it cannot oxidize any of the halides F2, Cl2, Br2, or I2. If the H+ ion concentration is increased, however, the driving force for the sulfuric acid reduction is also increased according to Le Châtlier's principle. Sulfuric acid cannot oxidize the...
