Question

What causes liquids to conduct electricity?

Answer 1

Impurities

Step-by-step explanation:

Purified water doesn't conduct electricity. What rather conducts electricity is the impurities in the water such as the salts. Socium chloride separates into positive and negatively charged ions when in a current and that is why Alessandro Volta used a salt solution in the creation of one of the first batteries ever.

Answer 2

Primarily what causes water to conduct electricity are the ions present in the water itself.
