Question

Consider given oxyacid anion and find which have two types of central atom with respect to oxidation state

S₂O₆²⁻, P₂O₇⁴⁻, S₂O₃²⁻, S₄O₆²⁻, S₂O₇²⁻, H₂P₂O₅²⁻, Cr₂O₇²⁻, S₂O₅²⁻

TestHub · Accepted Answer

1. S₂O₃²⁻: S oxidation states = +5 and -1

2. S₄O₆²⁻: S oxidation states = +5 and 0

3. S₂O₅²⁻: S oxidation states = +5 and +3

4. Remaining ions S₂O₆²⁻, P₂O₇⁴⁻, S₂O₇²⁻, H₂P₂O₅²⁻, Cr₂O₇²⁻ have the same oxidation state for both central atoms.

Total compounds having two oxidation states = 3
