If the concentration of Cu²⁺ ions in a Cu/Zn galvanic cell is increased, what is the expected effect on the cell potential and the direction of electron flow?

• A. Cell potential increases; electron flow remains the same.
• B. Cell potential decreases; electron flow remains the same.
• C. Cell potential decreases; electron flow reverses.
• D. Cell potential remains unchanged; electron flow reverses.

Answer: (A)
