**(A):** The oxidation state of Sulfur in is +8. <br> **(R):** contains one peroxide linkage. — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Assertion:** Sulfur cannot have an O.S. greater than +6 (its group number). The O.S. is actually +6. False. <br>**Reason:** $H_2SO_5$ (Caro's acid) does indeed contain one $-O-O-$ linkage, which is why calculation using $5 \times (-2)$ gives a wrong O.S. of +8. True.
