Tcecarenko [31]

Answer:

(a) Barium is produced at the negative electrode

(b) Iodine is produced at the positive electrode

Explanation:

When  an electric current is passed through a solution containing electrolyte, a non spontaneous reaction is stimulated. This results in the flow of <u>positively charged ions to negatively charged electrodes(</u><u>cathode</u><u>) and negatively charged ions to positively charged electrodes(</u><u>anode</u><u>)</u>

When an electric current is passed through molten BaI_{2} in the electrolytic cell, the following reactions takes place:

                                            BaI_{2} → Ba^{2+} + 2I^{-}

At the anode;

Iodine ions will lose an electron and will be oxidized to iodine

2I^{-} → I_{2} + e^{-}

At  the cathode;

Barium ions gains electrons and its reduced to barium metal

Ba^{2+} + 2e^{-} → Ba
