Question
Why must ionic compounds be molten or dissolved in water for electrolysis to occur?
Answer
Ionic compounds must be molten or dissolved in water to conduct electricity because in these states, the ions are free to move. In solid form, the ions are fixed in place within a lattice structure and cannot move to the electrodes.
Explanation
This answer explains the necessity of ionic compounds being in a molten or dissolved state for electrolysis, highlighting the importance of ion mobility. The question assesses the student's ability to apply their knowledge of ionic compounds and their states.
Common mistake
Misunderstanding Electrolysis Definition
Students often confuse electrolysis with simple chemical reactions, thinking it is just any reaction involving electricity rather than specifically the splitting of ionic compounds.
Emphasize that electrolysis specifically refers to the process of breaking down ionic compounds into their constituent ions using electricity.
