Question

What are the electrode products when molten silver iodide is electrolysed between inert electrodes. (give cathode answer and anode answer)

Answer 1

Answer:- $I_2$ at anode and Na at cathode.

Explanations:- We know that oxidation takes place at anode and reduction at cathode.

sodium iodide has $Na^+$ and $I^-$ ions. Iodide ion loses electron and get oxidized to form $I^-$ as:

$I^-\rightarrow \frac{1}{2}I_2+e^-$       (anode half reaction)

sodium ion goes to the cathode and reduced on accepting electron as:

$Na^++e^-\rightarrow Na$        (cathode half reaction)
