Fe rod becomes brightend when dipped in AgNo3 solution.why?
Asked by applee123 | 23 Nov, 2009, 10:56: AM
answered-by-expert Expert Answer

When Fe rod is kept in AgNO3 solution silver is reduced and gets deposted on iron. This is the reason when Fe rod appears to be brightened.

Given a choice between two species that species with higher reduction potential reduces in preference to the other species. 

Reduction potential of Ag+ /Ag is 0.79 V and that of Fe3+/Fe is -0.04 V.
