# A Cu/Cu2+ concentration cell has a voltage of 0.22 V at 298K. The concentration of Cu2+ in one of the half-cells is 1.6E−3 M. What is the concentration of Cu2+ in the other half-cell?

##### 1 Answer

#### Explanation:

Let us first describe the half-equations happening in the cell and write the overall equation:

**Anode** :

**Cathode** :

**Overall equation** :

For concentration cells, we can calculate the cell potential **Nernst Equation**:

Replacing the giving terms in this equation assuming that the given concentration is

and that

Solve for

Here is a video that explains in details the concentration cell and the Nernst Equation:
