Question

Substances A2, B2, and C2 can all act as oxidizing agents. In solution, A2 is green, B2 is yellow, and C2 is red. In the reactions in which they participate, they are reduced to A-, B-, and C ions, all of which are colorless. When a solution of B2 is mixed with one containing C ions, the color changes from yellow to red. a. Which species is oxidized? b. Which is reduced? When a solution of B2 is mixed with one containing A ions, the color remains yellow. c. Which species is a better oxidizing agent, B2 or A2? d. Which species is a better oxidizing agent B2 or C2? e. Arrange A2, B2, and C2 in order of increasing strength of oxidizing agent. weakest strongest

Answer 1

Az ts nean A on Colorloss on B2 is Yallou 2is red when a solo teon B is mtxed wsith Solution of cbn Color chanye from Yellow to Red B2 +20, 2Bt L2 Red Yellow a) Cis oxidized B2is meduced solution o B2 s mixed with one : Contarg A ion, when the color remaths yellow. A No veaction Yellow Thi's means , s hot able to ox{di2e A to A 2 C) Ar is beter oxidiaing agent than B is better oxidizing agent than Cr because S2s able to o Yid ize c 0 C2 e) The order o oxidy age vets s < Az Strouges Weakest
