An electrochemical cell consists of a standard hydrogen electrode and a copper metal electrode. (a) What is the potential of the cell at 25°C if the copper electrode is placed in a solution in which [Cu2+] = 3.0×10-4 M? 49 0.21 (b) If the copper electrode is placed in a solution of 0.43 M NaOH that is saturated with Cu(OH)2, what is the cell potential at 25°C? For Cu(OH)2, Ksn = 1.6x10-19. 4.0 (c) The copper electrode is placed in a solution of unknown [Cu2+ ]. The measured potential at 25°C is 0.210 V. What is [Cu2+ ]? (Assume Cu2+ is reduced.) 4.0 M.

Could I get help with this question (or at least the first few parts to get on the right track)?

An electrochemical cell consists of a standard hydrogen electrode and a copper metal electrode. (a) What is the potential of the cell at 25°C if the copper electrode is placed in a solution in which [Cu2+ ] = 3.0x10-4 M? 0.21 X V (b) If the copper electrode is placed in a solution of 0.43 M NaOH that is saturated with Cu(OH)2, what is the cell potential at 25°C? For Cu(OH)2, Ken = 1.6x10-19. 4.0 (c) The copper electrode is placed in a solution of unknown [Cu2+]. The measured potential at 25°C is 0.210 V. What is [Cu2+ ]? (Assume Cu2+ is reduced.) 4.0 (d) If you wish to construct a calibration curve to show how the cell potential varies with [Cu2+], what should you plot to obtain a straight line? O 8 versus [H*] O [Cu2+] versus log [H+]? O 8° versus [Cu2+] O [Cu2+] versus [H+] O 8 versus logl [Cu²+]) O 8 versus What will the slope of this line be if the temperature is 25°C? 4.0
