Question

show that with the help of activities acidic solution can conduct electricity with solution of glucose and alcohol do not conduct electricity

Answer 1

Answer:

Take solutions of glucose, alcohol, hydrochloric acid, sulphuric acid, etc.

Fix two nails on a cork, and place the cork in a 100 mL beaker.

Connect the nails to the two terminals of a 6 volt battery through a bulb and a switch.

Now pour some glucose solution in the beaker and switch on the current.

Repeat with alcohol solution and hydrochloric acid.

It is observed that bulb does not glow using glucose or alcohol solution. While if a solution of acid is used instead of glucose or alcohol solution, bulb glows.

Bulb glows when the solution of hydrochloric acid is used, because it dissociates into hydronium ion in aqueous solution. But glucose and alcohol do not dissociate hydronium ion in the water. Hence solution of glucose and alcohol do not conduct electricity.
