Chapter 24, Problem 24.4QAP
Halide ions can he deposited at a silver anode, the reaction being
Ag(s) + X-
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? (Take 1.00 × l0-5 M as the criterion for quantitative removal of an ion.) If a separation is feasible, what range of cell potential could he used?
(c) Repeat part (b) for I- and Cl-.
(d) Repeat part (b) for Br- and Cl-.
