  • question_answer The electrode potential of four metallic elements (A, B, C and D) are + 0.80, -0.76, +0.12 and +0.34 V respectively. Arrange them in order of decreasing electropositive character.


                    Higher the electrode potential \[(E{}^\circ )\] lower is the tendency of the metal to lose electrons and hence lower is the electropositive character of the metal. Since the electrode potentials increase in the order: ? 0.76 (B), + 0.12 (C), + 0.34 (D) and +0.80 (A), therefore, electropositive character decreases in the same order: B > C > D > A.
