A concentration cell has different concentrations of the same ions, but because of the different concentrations there is a very small voltage between the cells. This effect is especially problematic for corrosion. Consider the following overall reaction, which is assumed to occur in the presence of metallic iron: Fe3+(0.08M)Fe3+(0.001M) a What is E? b What is the expression for Q? c What is E for the concentration cell? d Should concentration cells be considered another type of colligative property? Explain your answer.
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?

(d) Repeat part (b) for Br- and Cl-.
Black-and-white photographic film is coated with silver halides. Because silver is expensive, the manufacturer monitors the Ag⁺ content of the waste stream, [Ag⁺]ᵥᵥₐₛₜₑ, from the plantwith an Ag-selective electrode at 25°C. A stream of known Ag⁺ concentration, [Ag⁺](standard), is passed over the electrode inturn with the waste stream and the data recorded by a computer.(a) Write the equations relating the nonstandard cell potential tothe standard cell potential and [Ag⁺] for each solution.(b) Combine these into a single equation to find [Ag⁺]ᵥᵥₐₛₜₑ.(c) Rewrite the equation from part (b) to find [Ag⁺]ᵥᵥₐₛₜₑ in ng/L.(d) If Eᵥᵥₐₛₜₑ is 0.003 V higher than E(standard), and the standard so-lution contains 1000. ng/L, what is [Ag⁺]ᵥᵥₐₛₜₑ?(e) Rewrite the equation in part (b) to find [Ag⁺]ᵥᵥₐₛₜₑ for a sys-tem in which T changes and Tᵥᵥₐₛₜₑ and T(standard) may be different.
The capacity of batteries such as the typical AA alkalinebattery is expressed in units of milliamp-hours (mAh). AnAA alkaline battery yields a nominal capacity of 2850 mAh.(a) What quantity of interest to the consumer is beingexpressed by the units of mAh? (b) The starting voltage of afresh alkaline battery is 1.55 V. The voltage decreases duringdischarge and is 0.80 V when the battery has delivered itsrated capacity. If we assume that the voltage declines linearlyas current is withdrawn, estimate the total maximumelectrical work the battery could perform during discharge.
