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
in the electrolytic cell, the following reactions takes place:
→
+ 2
At the anode;
Iodine ions will lose an electron and will be oxidized to iodine
→
+ 
At the cathode;
Barium ions gains electrons and its reduced to barium metal
+
→ Ba
