Questions & Step-by-Step Solutions
Which of the following statements is true about a concentration cell?
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 that are made of the same material.
Step 3: Recognize that the difference in concentration of the electrolyte solution at each electrode is what drives the cell's operation.
Step 4: Remember that the electrode with the higher concentration will undergo reduction, while the one with the lower concentration will undergo oxidation.
Step 5: Conclude that the statement 'A concentration cell has the same electrodes but different concentrations of the electrolyte' is true.
