Given below are the standard electrode potentials of few half-cells. The correct order of these metals in increasing reducing power will be
K+ | K = –2.93 V, Ag+ | Ag = 0.80 V, Mg2+ | Mg = –2.37 V, Cr3+ | Cr = –0.74 V.
K+ | K = –2.93 V, Ag+ | Ag = 0.80 V, Mg2+ | Mg = –2.37 V, Cr3+ | Cr = –0.74 V.
- K < Mg < Cr < Ag
- Ag < Cr < Mg < K
- Mg < K < Cr < Ag
- Cr < Ag < Mg < K
Answer
(B) Ag < Cr < Mg < K
