An electrochemical cell consists of a standard hydrogen electrode and a copper metal electrode. What is the potential of the cell at 25 °C if the copper electrode is placed in a solution in which [#Cu^(2+)#] = #2.5 x 10^-4# M)?
The copper electrode is placed in a solution of unknown #Cu^(2+)# . The measured potential at 25°C is 0.195 V. What is #Cu^(2+)# ? (Assume #Cu^(2+)# is reduced)
The copper electrode is placed in a solution of unknown
