Questions & Step-by-Step Solutions

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.
