Question

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+(aq)/Cu2+(aq)/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.

Answer 1

A

Step-by-step explanation:

True: When two metals are connected and placed in a solution containing both metal ions, the metal with the lower standard potential (more negative standard reduction potential) would tend to corrode or undergo oxidation.
