E^(@)valuesof Mg^(2+)//Mg "is" -2.37 V of Zn^(2+)//Zn is -0.76 V and Fe^(2+)//Fe:-0.44 V whichof the followingstatementis correct ?

Answer»

ZN will REDUCE`Fe^(2+)`
Znwill reduce `Mg^(2+)`
Mg oxidisesFe
Znoxidises Fe

Solution :Higher the negative value of `E^(@)` more is the reducing power the order of `E^(@)` VALUES (negative value ) is
`-2.37 GT -0.76 gt -0.44`
`therefore`Mg can reduce both`Zn^(2+)` and `Fe^(2+)`Zn can reduce`Fe^(2+)` but not `Ng^(2+)` Fe cannot reduce MGAND Zn but can oxidse them
