Be sure to answer all parts. In the electrolysis of molten BaI2, (a) What product forms at the negative electrode? (b) What prod

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 positively charged ions to negatively charged electrodes(cathode) and negatively charged ions to positively charged electrodes(anode)

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

$BaI_{2}$ → $Ba^{2+}$ + 2 $I^{-}$

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

From which category of elements would you choose to make a container that would not shatter if dropped? Explain your answer plea

Eduardwww [97]

Container must be made up of non metallic elements which can typically covalently bond and must have lone pairs of electrons dative bonds in order to allow further stability.
