(a) Interpretation Introduction Interpretation: The given species has to be arranged in decreasing order of strength as reducing agents. Concept Introduction: Oxidation: The gain of oxygen or the loss of hydrogen or the loss of an electron in a species during a redox reaction is called as oxidation. Reduction: The loss of oxygen or the gain of hydrogen or the gain of an electron in a species during a redox reaction is called as reduction. Oxidizing agent: The substance that is oxidized is called as a reducing agent. Reducing agent: The substance that is reduced is called as an oxidizing agent. Explanation Using the Appendix D the reduction potential for given species are noted as shown below, S O 4 2 − ( a q ) + 4 H + ( a q ) + 2 e − ⇌ S O 2 ( g ) + 2 H 2 O ( l ) E ∘ = + 0.20 V P b S O 4 ( s ) + H + ( a q ) + 2 e − ⇌ P b ( s ) + H S O 4 − ( a q ) E ∘ = − 0 (b) Interpretation Introduction Interpretation: The given species has to be arranged in increasing order of strength as reducing agents.
