Question

Standard Cell is constructed in which a Sn^2+ / Sn half cell act as the cathode.

A standard galvanic cell is constructed in which a Sn^2+ | Sn half cell acts as the cathode. Which of the following statements are correct? (Choose all that apply.) Cr^3+|Cr could be the other standard half cell. The cathode reaction is Sn rightarrow Sn^2+ + 2e^-. In the external circuit, electrons flow from the other compartment to the Sn^2+ |Sn compartment. Fe^3+|Fe^2+ could be the other standard half cell. As the cell runs, anions will migrate from the other compartment to the Sn^2+|Sn compartment.

Explanation / Answer

1) The cathod Reaction is Sn->Sn^2+ + 2e-

2) Fe^3+/Fe^2+ could be the other standard hlf cell.

3) As the cell runs, anions will migrate from the other comparment to the Sn^2+ I Sn.
