2. What is the electrical conductivity of acids and bases?
Acid and Bases have different different electrical conductivity based on density of free ions present in it. A strong acid/base conduct electricity easily. More strong means more the number of ions. Let us suppose, if you are connecting a bulb in a circuit with strong acid/base solution, bulb will glow accordingly.. if you are connecting it with weak acid/base solution, bulb will not glow significantly.
It just depends on strength of acid/base.Both can conduct electricity.
