Question

Different kinds of substances have different properties. How would I Compare and contrast the electrical properties of salts, metals, and acids?

Answer 1

Salts do not conduct electricity while metals and acids do.

Explanation:

Salts assuming you mean in solid state contain a giant ionic lattice structure in which oppositely charged ions are held in `fixed positions`, thus there are no charge carriers to carry electrical charges.

Metals contain a sea of electrons surrounding layers of metal cations, hence these `electrons` act as charge carriers allowing for electrical conductivity.

Acids assuming are dissolved, dissociate to form `H+` and the anion for example `Cl^-` in the case of `HCl` which results in free mobile ions in solution allowing for charge conductivity.
