Oxidation state of Cl in HClO₄ (perchloric acid):
A+5
B+7 (maximum oxidation state of Cl)
C+3
D+1
Answer & Solution
Correct answer: B. +7 (maximum oxidation state of Cl)
HClO₄: H(+1) + Cl(?) + 4 × O(-2) = 0. Cl = +7. Maximum oxidation state for Cl. Acid strength order: HClO < HClO₂ < HClO₃ < HClO₄ (perchloric acid is super-strong).
