SUMMARY
The discussion centers on determining the standard reduction potentials of half-cells, specifically regarding the reaction of Cu2+ ions in a CuSO4 solution stored in a tin container. Participants analyze the half-reactions Cu2+ + 2e- → Cu(s) and Cu2+ + e- → Cu+, referencing the Table of Standard Reduction Potentials. It is established that the reduction potential for Cu2+ to Cu(s) is higher than that for Cu2+ to Cu+, indicating that Cu2+ will preferentially reduce to solid copper rather than to the cuprous ion.
