Question
Question: The standard \(E^{o}\) values of few redox couples are \[Zn^{2 +}/Zn = - 0.76V,Ag^{+}/Ag = + 0.80V,...
The standard Eo values of few redox couples are
Zn2+/Zn=−0.76V,Ag+/Ag=+0.80V,Cu2+/Cu
=0.34V.
Choose the correct option.
A
Ag can oxidize Zn and Cu.
B
Ag can reduce Zn2+ and Cu2+
C
Zn can reduce Ag+and Cu2+
D
Cu can reduce Zn2+and Ag+
Answer
Zn can reduce Ag+and Cu2+
Explanation
Solution
: Zince can reduce Ag+ and Cu2+ due to lowest reduction potential.
