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?

Answer 1

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

Answer 2

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