Question

How can we test that liquids conduct electricity?​

Answer 1

Explanation:

Immerse the two free ends of the wires into a beaker containing water or any liquid without touching each other. If the LED glows, the liquid conducts electricity. If the LED does not glow, the liquid does not conduct electricity. If the brightness of the LED glow is high, then those liquids are good conductors.
