In a galvanic system: where two electrodes of the same metal (M) are immersed in two different solutions of the same metal (M), the system where the concentration of Mⁿ⁺ is smaller will be the cathode according to the Nernst equation. Isn't this against Le Chatelier's principle? I mean, the solution with a smaller amount of the metal ions, will have its ions precipitate at the cathode. How?

That's not true, the potential of the electrode with the higher concentration of Mⁿ⁺ will be higher, and hence that electrode will be the cathode. All in accordance with Le Chatelier. Can you please show your reasoning of how you got to your conclusion? I'm expecting a sign problem in the Nernst, happened to me a million of times.

True. Thank.
