Answer: A solid silver, Ag, conducts electricity because it contains ions or electrons while solid silver chloride, AgCl, does not conduct electricity because AgCl does not dissociate to give ions or electrons.
Explanation:
Solid silver (Ag) is considered to be a good conductor of electricity because there are more number of free electrons or movable atoms are present in it.
As electricity is the flow of ions or electrons. So, more is the number of ions or electrons present in a substance more will be its conductivity.
Whereas solid silver chloride is a precipitate that is insoluble in water and therefore, it will not give ions or electrons.
As a result, silver chloride is not able to conduct electricity.
