Answer:
i) Solutions of acids and bases are often good conductors of electricity because when dissolved in water, they form/separate into ions (anions and cations) which are ideal for conducting electricity.
Explanation:
Solutions that conduct electricity have ions in them. These ions allow for the current to pass through the solution.
Strong acids completely dissociate into
H
+
ions and some other (-) charged counter ion. In this way, a solution of simple acid like HCl that is 1M, for example, will be 2 M in total ions (1M + ions, 1M (-) ions). These ions allow the solution to conduct electricity.
