Concentration Cells

[Gwyneth Huynh 1J]

If we're given a concentration cell of Ag+ with 0.10 M of Ag+ and 2.0 M Ag+ solutions, would the anode or the cathode have the higher concentration?

[Christiana2D]

The higher concentration ion would be the cathode, assuming it's on the right. In the book on page 589, it states that if the concentration of the left-hand electrode ions is less than the concentration of the right-hand electrode ions and the potential difference, E, is positive, then the right-hand electrode is the cathode.

[Katelyn B 2E]

The anode would have the solution with a lower concentration and the cathode would have the solution with a higher concentration. If you want an explanation as to why, this Khan Academy video offers a great one!
