A peroxy acid (often spelled as one word, peroxyacid, and sometimes called peracid) is an acid in which an acidic -OH group has been replaced by an -OOH group. They are formed chiefly by elements in groups 14, 15 and 16 of the periodic table, though boron and certain transition elements are also known to form peroxy acids. Sulfur and phosphorus form the largest range of peroxy acids, including some condensed form such as peroxydiphosphoric acid, H4P2O8 and peroxydisulfuric acid, H2S2O8.
