Problem

Peroxodisulfuric acid is an unusual molecule because it contains an oxygen–oxygen single bond ($\text{O}–\text{O}$), which is quite rare and unstable in aqueous solution. When you hydrolyze it, that weak $\text{O}–\text{O}$ bond breaks apart, and water molecules attack the sulfur centers to form more stable products. The key is recognizing that hydrolysis will cleave the peroxide linkage and convert the sulfur atoms into their typical oxidation states found in common sulfur oxyacids.
