Question

Which of the following statements are correct concerning redox properties?
(i) A metal M for which E° for the half life reaction $Mn^+ + ne^- \rightleftharpoons M$ is very negative will be a good reducing agent.
(ii) The oxidizing power of the halogens decreases from chlorine to iodine.
(iii) The reducing power of hydrogen halides increases from hydrogen chloride to hydrogen iodide
(a) (i), (ii) and (iii)
(b) (i) and (ii)
(c) (i) only
(d) (ii) and (iii)

Answer 1

c because one option also corrects

Answer 2

a option 1 is correct becaz highly -ve reducion potential is oxidised so it act as redusing agent 2. oxidising nature is decreses from top to botton in halogen group and reducing nature is increases
