The O-O linkage is present in__________?
Correct answer: B. H2SO8
- A. H2S2O3
- B. H2SO8
- C. H2S4O6
- D. H2 S2 O6
Explanation
H2SO8 contains a peroxide O-O linkage, represented in its structure as a peroxodisulfuric acid unit. Students may choose H2S2O3 because its formula contains two sulfur atoms, but that does not mean it contains an O-O bond.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
