Adding powdered Pb and Fe to a solution containing 1.0 M each of `Pb^(2+)` and `Fe^(2+)` ions would result into the formation of:

Options

A. More of Pb and `Fe^(2+)` ions
B. More of Fe and `Pb^(2+)` ions
C. More of Fe and Pb
D. More of `Fe^(2+)` and `Pb^(2+)` ions

Answer

A

Explanation

`E_(Pb^(2+)//Pb)^(@)gtE_(Fe^(2+)//Fe)^(@)` so, Fe will oxidise and `Pb^(2+)` will reduce.
