State which of the following statements are true: a) When two metals, e.g. Zn and Cd, are connected and placed in a solution containing both metal ions, the metal with the lower standard potential would corrode. b) Conversely, the metal with the higher potential would be deposited. c) The cell and cell reaction are written in opposite orders, for instance, for the cell Fe/Fe2*(ag)/Cu²"(ag)/Cu, the reaction is Fe2+ + Cu>Cu2+ +Fe d) The cell potential is obtained by subtracting the electrode potential of the right-hand electrode from the left-hand electrode.

Transcribed Image Text:State which of the following statements are true:
a) When two metals, e.g. Zn and Cd, are connected and placed in a
solution containing both metal ions, the metal with the lower
standard potential would corrode.
b) Conversely, the metal with the higher potential would be deposited.
c) The cell and cell reaction are written in opposite orders, for instance,
for the cell Fe/Fe2*(ag)/Cu2"(ag)/Cu, the reaction is
Fe2+ + Cu>Cu2+ +Fe
d) The cell potential is obtained by subtracting the electrode potential of
the right-hand electrode from the left-hand electrode.
