Avoltaic cell is constructed with two silver-silver chloride electrodes, where the half-reaction isagcl (s) + e- ? ag (s) + cl-(aq) e° = +0.222 vthe concentrations of chloride ion in the two compartments are 0.0156 m and 1.55 m, respectively. the cell emf is v. a 0.232b 22.1c 0.212d 0.00223e 0.118

Answer : The cell emf for this cell is 0.118 V

Solution :

The balanced cell reaction will be,  

Oxidation half reaction (anode):  

Reduction half reaction (cathode):  

In this case, the cathode and anode both are same. So, is equal to zero.

Now we have to calculate the cell emf.

Using Nernest equation :

where,

n = number of electrons in oxidation-reduction reaction = 1

= ?

= 0.0156 M

= 1.55 M

Now put all the given values in the above equation, we get:

Therefore, the cell emf for this cell is 0.118 V
