A galvanic cell was constructed with a nickel electrode that was dipped into 1.2 M NISO4 solution and a chromium electrode that was immersed into a solution containing Cr+ at an unknown concentration. The potential of the cell was measured to be 0.538 V, with the chromium serving as the anode. The standard cell potential for this system was determined to be 0.487 V. What was the concentration of Cr3+ in the solution of unknown concentration? [Cr3+] = i M

Halide ions can he deposited at a silver anode, the reaction being Ag(s) + X- AgX(s) +e- Suppose that a cell was formed by immersing a silver anode in an analyte solution that was 0.0250 M Cl-,Br-, and I -ions and connecting the half-cell to a saturated calomel cathode via a salt bridge. (a) Which halide would form first and at what potential? Is the cell galvanic or electrolytic? (b) Could I- and Br- be separated quantitatively?
