## Consider the concentration cell shown below. Calculate the cell potential at 25°C when the concentration of Ag+ in the compartment on the right is the following.a. 1.0 Mb. 2.0 Mc. 0.10 Md. 4.0 × 10−5 Me. Calculate the potential when both solutions are 0.10 M in Ag+.For each case, also identify the cathode, the anode, and the direction in which electrons flow. (a)

Interpretation Introduction

Interpretation:

The set up of a concentration cell is given. The value of cell potential at 25°C for different concentration of Ag+ in the compartment on the right is to be calculated.

Concept introduction:

When the transport of substance occurs from one half cell to another due to difference in concentration gradient there occurs generation of current. This leads to the formation of concentration cells.

They are of two types,

• Electrode concentration cell
• Electrolyte concentration cell

The difference in ion concentration in different compartments decides the direction of electron flow and helps in assigning the position of anode and cathode.

To determine: The cell potential at the 1.0M concentration of Ag+ in right compartment and the cathode and anode and the direction of electron flow.

### Explanation of Solution

The value of overall cell potential is zero and there occurs no flow of electrons and the position of cathode and anode cannot be specified.

The concentration of Ag+ in left compartment is 1.0M and in right compartment is also 1.0M . Therefore no flow of electrons will occur and the position of cathode and anode cannot be specified.

The value of Ecell is calculated using Nernst formula,

E=E°(RTnF)ln(Q)

At room temperature the above equation can be specifies as,

E=E°(0.0591n)log(Q)

Where,

• E is the cell potential
