Many applications of electrochemistry have been in chemical analysis. Suppose a Fe|Fe+ concentration cell is set-up in which the [Fe2*] = 1.0 x 10 M in one compartment but the concentration in the other compartment is unknown. The Ecell was measured at o.024V when the half-cells were connected. (i) Without doing a numerical calculation, is the unknown more or less concentrated than the 1.0 x 10 ² M solution? Justify your answer (ii) Calculate the unknown concentration. (iii) Does your calculated answer agree with your original answer? Why?
