Question
Explain why a solid ionic compound does not conduct electricity.
Answer
A solid ionic compound does not conduct electricity because the ions are held in a fixed position within the giant ionic lattice and cannot move freely. Since electrical conductivity requires the movement of charged particles, the immobility of the ions in the solid state prevents the conduction of electricity.
Explanation
This answer is strong because it clearly identifies the reason for the lack of electrical conductivity in solid ionic compounds, linking it to the structure of the ionic lattice and the mobility of ions. The question tests the student's understanding of the properties of ionic compounds and their relationship to structure.
Common mistake
Misunderstanding Ionic Conductivity
Students often think that solid ionic compounds can conduct electricity because they contain charged ions.
Emphasize that in solid ionic compounds, ions are fixed in place within the lattice structure and cannot move to conduct electricity.
