pure solid for electrodes
1 atm pressure for gases
Which of the cell notation is CORRECT for this redox equation:
2Ag+(aq) + Cu(s) --> Cu2+(aq) + 2Ag(s)
Cu(s) │ Cu2+(aq, 1M) ║ 2Ag+(aq, 1M) │ 2Ag(s)
Cu(s) │ Cu2+(aq, 1M) ║ Ag+(aq, 1M) │ Ag(s)
Ag(s) │ Ag+(aq, 1M) ║ Cu2+(aq, 1M) │ Cu(s)
2Ag(s) │ 2Ag+(aq, 1M) ║ Cu2+(aq, 1M) │ Cu(s)
