Unformatted text preview: g ) + 4 H 2 O ( l ) + 3 Cu 2+ ( aq ) Label the anode and the cathode and write a balanced -reaction for each. Indicate the direction of e-flow. Use a table of standard reduction potentials to calculate the overall cell potential. Based on your result, will this cell indeed be spontaneous and produce current? 4. For each of the following pairs, determine whether transfer of e-will occur (will a spontaneous redox reaction occur)? Youll want to use data from a table like 18.1 to get standard reduction potentials for reactions that involve each of the species. Do the cell potentials sum up to yield a positive cell potential (thus spontaneous)? a) Ca 2+ ( aq ) and Zn ( s ) b) Ag + ( aq ) and Ni ( s ) c) Mn 2+ ( aq ) and Fe ( s ) d) Pb 2+ ( aq ) and Al ( s )...
