Question
During the electrolysis of molten sodium chloride, what are the products formed at the cathode and anode?
Answer
At the cathode, sodium metal (Na) is produced, and at the anode, chlorine gas (Cl2) is produced.
Explanation
This question assesses the student's ability to predict the products of electrolysis based on the ionic composition of the molten compound. It requires understanding of the movement of ions and their discharge at electrodes.
Common mistake
Common Mistake in Writing Word Equations
Students often forget to include the states of the reactants and products in their word equations for electrolysis.
Always specify the physical states of the substances (e.g., solid, liquid, gas) when writing word equations to provide a complete representation of the reaction.
