A concentration cell consists of two Al/Al+3 electrodes. The electrolyte in compartment A is 0.05M Al(NO3)3 and in compartment B is 1.25 M Al(NO3)3. What is the voltage of the cell at 25 degrees Celcius?

ECell = EoCell-(0.059/n)log(dilute soln/concd soln) EoCell = 0. n = 3. Substitute and solve.

I know that this is an old thread, but if dilute soln/concd soln, then the answer is negative.
