Sulfuric acid and hydrogen peroxide mixed together create a powerful cleaning and etching agent, famously known as Piranha Solution, used to remove organic residues, but it's extremely hazardous due to intense heat (exothermic reaction) and aggressive oxidation, generating Caro's acid (peroxymonosulfuric acid) and free radicals, requiring strict safety protocols. They are also used in metallurgy and electronics for surface treatment, where H2O2 enhances H2SO4's ability to dissolve stubborn materials or act as a strong oxidant, with careful control of temperature and concentration being crucial for safety and effectiveness.
