WebPiranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2).The result of the mixture gives rise to a strong union of two acids called per-hexa-sulfuric acid (H 4 SO 6) that is used to clean organic residues off substrates. Because the mixture is a strong oxidizing agent, it will decompose most … WebThe reaction is carried out using concentrated sulfuric acid (H2SO4) as the sulfonation agent and a catalyst. The mechanism of sulfonation is similar to nitration, but the electrophile in this case is the sulfur trioxide(SO3) molecule, which is generated in situ from the reaction between sulfuric acid and an oxidizing agent.
