QAIPM-2001-Ch-2863: NEET 2001 Chemistry - Class 12 AIPM-2001-Ch-2863 Solution: Standard electrode potentials are $Fe^{2+}/Fe [E^ =-0.44]$…

Standard electrode potentials are

Fe^{2+}/Fe [E^\circ=-0.44]

and

Fe^{3+}/Fe^{2+} [E^\circ=0.77]

; If

Fe^{2+}

Fe^{3+}

and Fe blocks are kept together, then

Step-by-Step Verified Solution

The metals having higher negative values of their electrode potential can displace metals having lower values from their salt solutions.
