Standard Reduction Potentials of 1/2 Cells

Click For Summary
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.

The Attempt at a Solution


My question isn't exactly how to do this question. I was just wondering, how can you tell whether the Cu2+ ion will react in this way: Cu2+ + 2e- ---> Cu(s) or whether it will react like this: Cu2+ + e- ---> Cu+ ?
 
Physics news on Phys.org
Which has the greater standard reduction potential? The one for cuprous ion or the one for the tin ion? Check in you table of standard reduction potentials.
 
well then how do u know Cu2+ will ever react to form Cu+? Because the reaction that yields Cu(s) always has a high reduction potential.
