Chem 103A Electrochemistry 8. Consider a voltaic cell that uses the reaction Cu(s) + 2Fe'(aq) - Cr"(aq) + 2Fe""(aq) What is the potential of a cell at 25°C that has the following concentrations? [Fe'') - 1.0x 10M (Cu)-0.25 M [Fe] =0.20 M 9. Lead can displace silver from solution, and as a consequence, silver is a valuable by-product in the industrial extraction of lead from its ore: Pb(s) + 2 Ag" (aq) → Pb...
