Can Cr3+ oxidize Ag(s) ?
Can Cr3+ oxidize Ag(s) ?
Homework Answers
standard reduction potential values of both species are given below
Cr3+ + 3 e−---->Cr(s) E0= −0.74 V
Ag+ + e− ---.>Ag(s) +0.7996 V
The one with higher reduction potential will under go reduction
. Here Ag has higher
reduction potential value. So it will undergo reduction when
coupled with Cr
Thus Cr3+ can not oxidize Ag
