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 MnO2,,,,but im not sure if its right...can someone confirm it?
thx

Yes, MnO2 will produce the largest standard cell voltage when combined with cupric ions. This is because the standard cell voltage for MnO2 (s) /Mn2+ (aq, 1M) with cupric ions (aq, 1M) is 1.51 V, which is the highest out of the four options.
