The standard reduction potential values ...

The standard reduction potential values of there metallic cations `X, Y, Z` are `0.52,-3,03` `-1.18 V` respectively. What will be the order of reducing power of the corresponding metals?

Text Solution

Verified by Experts

Reducing power is measure of the tendency for oxidation. The oxidation potentials of X.Y and. `Z` are `-0.52 .+3.03` and `+1.18 ~V`.respectively. The tendency `_4` of oxidation is greater if the oxidation potential is greater. Hence the order of reducing power is `YgtZgtX` des.
