The correct answer is option (B): H2SO5 and H2S2O8
Peroxoacids of sulfur are inorganic acids that have both peroxy and acidic functional groups. They are formed by the combination of hydrogen peroxide with oxoacids of sulfur. The two peroxosulfhuric acids are Peroxomonosulphuric Acid: Which has the chemical formula of H2SO5. It is a strong oxidizing acid also called Caro’s Acid. Peroxodisulfuric acid (H2S2O8): It is also known as Marshall’s acid and is a powerful oxidizing and dehydrating acid. They are both highly reactive.
