A cell is prepared by dipping the Cu rod in M `CuSO_(4)` solution and the Zn rod in 1 M `ZnSO_(4)` solution . The standard reduction potentials of copper and zinc are 0.34 V and - 0 . 76 V , respectively .

Options

A. What will be the cell reaction ?
B. What will be the standard EMF of the cell ?
C. Which electrode will be positive ?
D. How will the cell be represented ?

Explanation

(a) Anode : `Zn(s) to Zn^(2+)(aq)+2e^(-)`
Cathode : `Cu^(2+)(aq)+2e^(-) to Cu(s)`
(b) EMF of the cell =+1.10 V
(c ) Copper electrode acts as positive electrode
(d) `Zn(s)|Zn^(2+)(aq)||Cu^(2+)(aq)|Cu(s)`
