Which element could be formed at the anode when a molten salt is electrolysed?
When a molten salt is electrolyzed, the element that could be formed at the anode is typically a halogen, such as chlorine or fluorine, depending on the composition of the salt. During the electrolysis process, anions migrate to the anode, where they are oxidized, releasing their electrons and forming gases. For example, in the electrolysis of sodium chloride (NaCl), chlorine gas (Cl₂) is produced at the anode.
Why do you use molten NaCl in electrolysis instead of an aqueous solution of NaCl?
Molten NaCl is preferred over an aqueous solution of NaCl in electrolysis because in the molten state, NaCl dissociates into Na+ and Cl- ions without the presence of water molecules, allowing for direct electron transfer at the electrodes. In an aqueous solution, water molecules also undergo electrolysis, leading to the production of hydrogen gas and oxygen gas, which can interfere with the desired reactions involving Na+ and Cl- ions. Additionally, the high melting point of NaCl ensures that it remains in the molten state during the electrolysis process, providing a stable environment for the reactions to occur.
What happens at the negative electrode during the electrolysis of molten aluminium?
At the negative electrode during the electrolysis of molten aluminum, aluminum ions in the molten aluminum are reduced to form liquid aluminum metal. This process occurs as a result of the transfer of electrons to the aluminum ions, causing them to gain electrons and be converted into the metallic form.
