Current is applied to a molten mixture of PbF2, NiCl2, and MgI2

What is produced at the cathode?

Cl2, F2, Mg, Pb, Ni, I2

What is produced at the anode?

I2, Pb, Cl2, F2, Ni, Mg

please explain as well. i also want to learn how.

Answer #1

At cathode reduction happens

Cations move towards cathode and redcution ahppnes there , Pb2+ , Ni2+ , Mg2+ move towards cathode.

We check for standard reduction potential values of Eo(Pb2+/Pb) , Eo(Ni2+.Ni) , Eo(Mg2+/Mg) form table and whose reduction potential is higher value that species undergoes reduction.

Eo(Pb2+/Pb) is higher value of of three cations , hence Pb2+ undergoes reduction and we get Pb(s)

Rb2+ + 2e- --->Pb(s)     

Now at anode oxidation occurs , so anions move towards anode , i.e F- , Cl- , I- ,

now whose reduction potential is lowest that species has greatest tendancy of getting oxidised.

Eo( F2/2F-) , Eo(Cl2/Cl-) , Eo(I2/2I-) are compared , we see that Eo(I2/2I-) is less of three

hence at anode we have   2I- (aq) ---> I2 + 2e-

thus I2 is produced at anode.
