KO2, Na,02, 03, KMnO4, HI, NH3, K,Cr2O7.​

Answer 1

Answer:

$The redox reaction :</p><p></p><p></p><p>5ClO3−+3As2S3+9H2O⟶5Cl−+6H++6H2AsO4−+9S↓</p><p></p><p>The oxidation number of Cl decreases from +5 to -1. </p><p></p><p>Thus, chlorine is reduced.</p><p>Hence, ClO3− acts as oxidizing agent.</p><p></p><p>The oxidation number of As increases from +3 to +5. </p><p></p><p>Thus, As is oxidized.</p><p>Hence, As2O3 acts as reducing agent.</p><p></p><p>$
