Question

Question: The standard \(E^{o}\) values of few redox couples are \[Zn^{2 +}/Zn = - 0.76V,Ag^{+}/Ag = + 0.80V,...

The standard EoE^{o} values of few redox couples are

Zn2+/Zn=0.76V,Ag+/Ag=+0.80V,Cu2+/CuZn^{2 +}/Zn = - 0.76V,Ag^{+}/Ag = + 0.80V,Cu^{2 +}/Cu

=0.34V.= 0.34V.

Choose the correct option.

A

Ag can oxidize Zn and Cu.

B

Ag can reduce Zn2+Zn^{2 +} and Cu2+Cu^{2 +}

C

Zn can reduce Ag+Ag^{+}and Cu2+Cu^{2 +}

D

Cu can reduce Zn2+Zn^{2 +}and Ag+Ag^{+}

Answer

Zn can reduce Ag+Ag^{+}and Cu2+Cu^{2 +}

Explanation

Solution

: Zince can reduce Ag+Ag^{+} and Cu2+Cu^{2 +} due to lowest reduction potential.
