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 If we assume that the voltage declines linearlyas current is withdrawn, estimate the total maximumelectrical work the battery could perform during discharge.

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.
