Answer» 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. |
