Which of the following statements about redox behavior are true?
(i) A metal M whose standard reduction potential for the half-reaction Mⁿ⁺ + ne⁻ ⇌ M is highly negative acts as a strong reducing agent.
(ii) The oxidizing strength of the halogens falls in the order chlorine to iodine.
(iii)

Question

Which of the following statements about redox behavior are true?
(i) A metal M whose standard reduction potential for the half-reaction Mⁿ⁺ + ne⁻ ⇌ M is highly negative acts as a strong reducing agent.
(ii) The oxidizing strength of the halogens falls in the order chlorine to iodine.
(iii) The reducing strength of hydrogen halides rises from hydrogen chloride to hydrogen iodide.

Accepted Answer

(i), (ii) and (iii). All three statements are correct: a highly negative standard reduction potential indicates a strong tendency to lose electrons, making the metal a strong reducing agent; the oxidizing strength of halogens decreases from chlorine to iodine due to their decreasing electronegativity; and hydrogen halides become stronger reducing agents as the bond strength decreases from HCl to HI.
