Please do I do rate :)
A standard galvanic cell is constructed with F2|F and Sn2+\Sn half cell compartments connected by a salt bridge. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) Sn is oxidized at the anode. Sn2+ is reduced at the cathode. As the cell runs, anions will migrate from the Sn2+\Sn compartment to the F2|F" compartment. In the external circuit, electrons flow from the Sn2+\Sn...
