Given,

$straight E subscript Cl subscript 2 divided by Cl to the power of minus end subscript superscript 0 space equals 1.36 space comma straight E subscript Cr to the power of 3 plus end exponent divided by Cr end subscript superscript 0 space equals space minus 0.74 space straight V straight E subscript Cr subscript 2 straight O subscript 7 superscript 2 minus end superscript end subscript superscript 0 space equals space 1.33 space straight V comma straight E subscript MnO subscript 4 superscript minus divided by Mn to the power of 2 plus end exponent end subscript superscript 0 space equals space 1.51 space straight V$
Among the following, the strongest reducing agent is

Cr

Mn²⁺

Cr³⁺

Cl^-

Solution

Cr⁺³ is having least reducing potential, therefore Cr is the best Reducing agent.
