Question

Which of the following statements is incorrect?

  1. Acids are bad conductors of electricity.
  2. The ions are free to move about in an electrolyte.
  3. An electric bulb glows due to the heating effect of current.
  4. The solution which can form ions is used for electroplating.

hintHint:

The acids are good conductors.

The correct answer is: Acids are bad conductors of electricity.


    • The acids are good conductors.
    • The ionic composition of the acid helps the flow of current.
    • The addition of acids in distilled water makes it a good conductor.
