$Cu$

Vedclass · Answer

(D) In the electrochemical series,$Cu$ is placed below hydrogen. Hence,it has a positive value of standard reduction potential $(E^{\circ}_{M^{2+}/M})$.The standard reduction potentials for the given elements are:$Ti (Z=21) \Rightarrow -1.63 \ V$$Cr (Z=24) \Rightarrow -0.90 \ V$$Ni (Z=28) \Rightarrow -0.257 \ V$$Cu (Z=29) \Rightarrow +0.337 \ V$Comparing these values,the highest reduction potential is of $Cu$ because it is the only one with a positive value,while $Ni$,$Cr$,and $Ti$ have negative reduction potential values.

List-$I$ ($\text{Transition metal ion}$)	List-$II$ ($\text{Spin only magnetic moment (B.M.)}$)
$A$. $Ti^{3+}$	$I$. $3.87$
$B$. $V^{2+}$	$II$. $0.00$
$C$. $Ni^{2+}$	$III$. $1.73$
$D$. $Sc^{3+}$	$IV$. $2.84$

The element with the highest standard reduction potential (in volt) for the process $M^{2+} \rightarrow M$ among the first row of transition elements is:
