When combined with cupric ions (aq, 1M) which will produce the largest standard cell voltage? (Use data from table 20.1, and Appendix D page A28-A29 in Petrucci)
1. ) Mn(s)
2. ) MnCl2(aq)
3. ) KMnO4(aq)
4. ) MnO2(s)

the answer i got was MnCl2,,,,but im not sure if its right...can someone confirm it?

what is going to reduce Cu2+ ions then if all you have are Cl- ions (does not like being oxidized) and Mn2+ ions (wants to be reduced not oxidized)

so would the answer be Mn (s)?
