Problem- A concentration cell is constructed by placing identical iron electrodes in two Fe2+ solutions. The potential of this cell is observed to be 0.047 V. If the more concentrated Fe2+ solution is 0.10M, what is the concentration of the other Fe2+ solution?
Please show the entire work. I am thanking you in advance
