Question: In a concentration cell, the potential difference arises due to:

Options:

Correct Answer: Different concentrations

Solution:

In a concentration cell, the potential difference arises due to different concentrations of the same species.

In a concentration cell, the potential difference arises due to:

In a concentration cell, the potential difference arises due to:

Correct Answer: Different concentrations of the same species

Step 1: Understand what a concentration cell is. It is a type of electrochemical cell.
Step 2: Know that a concentration cell has two electrodes made of the same material.
Step 3: Recognize that the two electrodes are placed in solutions with different concentrations of the same ion or species.
Step 4: Realize that the difference in concentration creates a difference in chemical potential.
Step 5: Understand that this difference in chemical potential leads to a potential difference (voltage) between the two electrodes.
Step 6: Conclude that the potential difference arises because the ions move from the area of higher concentration to the area of lower concentration.

Concentration Cell – A type of electrochemical cell where the electrodes are made of the same material but are in different concentrations of the same ion.
Nernst Equation – The equation that relates the concentration difference to the cell potential, highlighting how potential difference arises from concentration gradients.
