Worked Solution & Example Answer:Sodium chloride is an ionic compound - Edexcel - GCSE Chemistry - Question 2 - 2018 - Paper 1
Step 1
Which row of the table correctly shows the ability of sodium chloride to conduct electricity when solid, molten and in solution?
Answer
The correct answer is A: When sodium chloride is solid, it does not conduct electricity. In molten form, it conducts electricity due to the free movement of ions, and in solution, it also conducts electricity since the ions are free to move in the liquid state.
