What product(s) forms at the anode in the electrolysis of an aqueous solution of Na3PO4?

What product(s) forms at the anode in the electrolysis of an aqueous solution of FeI2?
How do you solve both of these and what is the difference between them?

Solutions

Expert Solution

forms at the anode in the electrolysis of an aqueous solution of Na3PO4.

In general, the least active ion (ions having lower discharge potential) is discharged first at anode. ion is less active than ion. Hence, it is discharged first at anode.

Note: The discharge potentials for and ions are -0.276 V and -1.2 V respectively.


Iodine forms at the anode in the electrolysis of an aqueous solution of FeI2.

In general, the least active ion (ions having lower discharge potential) is discharged first at anode. ion is less active than ion. Hence, it is discharged first at anode.

Note: The discharge potentials for and ions are 0.54 V and -1.2 V respectively.
