QAIPM-2012-Ch-1635: NEET 2012 Chemistry - Class 12 AIPM-2012-Ch-1635 Solution: Four successive members of the first series of the transition…

Four successive members of the first series of the transition metals are listed below. For which one of them the standard potential (

E_{M^{2+}/M}^\circ

) value has a positive sign? Co (Z = 27) Ni (Z = 28) Cu (Z = 29) Fe (Z = 26)

Step-by-Step Verified Solution

( E C o 2 + / C o o ) = -0.28 ( E N i 2 + / N i o ) = -0.25 ( E C u 2 + / C u o ) = +0.34 ( E F e 2 + / F e o ) = -0.44
