A standard galvanic cell is constructed in which a Ni?+ | Ni half cell acts as the cathode. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) Hg2"Hg could be the other standard half cell. The cathode reaction is Ni > Ni2+2e Mg2+Mg could be the other standard half cell. As the cell runs anons will migrate from the Ni2+ Ni compartment to the other compartment. The anode reaction could be Mg > Mg?- +2e 6 9 more group attempts remaining Retry Entire Group Submit Answer

Explanation / Answer

SRp of Cr is -0.74V and SRP of F2 is +2.87 V

Hence The cell is

2Cr +3 F2 --------->2 Cr+3 + 6 F-

Thus Cr is oxidised and F2 is reduced.

that is Cr is the anode and F2 is the cathode.

4) In the external circuit electrons flow from Cr+/Cr electrode to F2/F- compartment.

the correct options are

2) F2 is reduced at the cathode
