Question

How can you test whether lemon juice is good conductor or poor conductor of electricity?

Answer 1

Lemon juice will conduct electricity because of small amounts of acids present in it.

However,we can test it by a simple activity:

(1) Take lemon juice.
(2) Fix two nails on a cork ,and place the cork in a 100 ml beaker.
(3) Connect the nails to the two terminals of a 6 V battery through a bulb and a switch.
(4) Now pour some lemon juice in the beaker and switch on the current.

Observation:
You will notice that the bulb glows

Result:
We can say that lemon juice is poor conductor of electricity ( however they conduct electricity).
