Question: If the concentration of Cu²⁺ in a cell is increased, what happens to the cell potential?

Options:

Correct Answer: Increases

Solution:

Increasing the concentration of Cu²⁺ increases the cell potential according to the Nernst equation.

If the concentration of Cu²⁺ in a cell is increased, what happens to the cell potential?

If the concentration of Cu²⁺ in a cell is increased, what happens to the cell potential?

Step 1: Understand that a cell potential is a measure of the voltage produced by a chemical reaction in a cell.
Step 2: Know that Cu²⁺ is a copper ion that can participate in a redox reaction in the cell.
Step 3: Recognize that increasing the concentration of Cu²⁺ means there are more copper ions available for the reaction.
Step 4: Remember the Nernst equation, which relates the concentration of ions to the cell potential.
Step 5: Realize that according to the Nernst equation, increasing the concentration of Cu²⁺ will lead to an increase in the cell potential.
Step 6: Conclude that if the concentration of Cu²⁺ is increased, the cell potential will also increase.

Nernst Equation – The Nernst equation relates the concentration of ions in solution to the cell potential, indicating that an increase in ion concentration can lead to an increase in cell potential.
Electrochemical Cells – Understanding how changes in ion concentration affect the behavior of electrochemical cells is crucial for predicting cell potential.
