Answer 1

Answer #1

Solution:

c) Option (Ni)

The metal which posses more negative reduction potential is most reactive because of highest reducing property. Since, out of given metals Ni posses negative reduction potential, hence Ni is most reactive metal.

d) Option (SO4^2-)

The SO4^2- anion is least reactive because it posses less positive reduction potential, hence its oxidising property is less than MnO4- and Cr2O7^2- ions.
