### Concentration Cells

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?

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.

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!
