Question

Why does a bulb glows dimly when current passed through a solution of vinegar?

Answer 1

When an ​electric current is passed through vinegar taken in a beaker ,then the bulb glows very dimly. The very dim glowing of bulb indicates that though vinegar and lemon juice conduct electricity but they are weak conductors of electricity.

Answer 2

when current passed through a solution of vinegar a bulb glows dimly because vinegar contains acetic acid.Acetic acid is weak acid as well as weak electrolyte.In aqueous solution, it dissociates in very small extent to give hydronium ions and acetate ions.Hence a small amount of electricity passes through it and shows very low conductivity.
