Question

While testing the conductivity of water in a beaker, it is observed that the bulb in beaker does not glow. Give a reason for it.

Answer 1

When common salt (NaCl) is dissolved in water, it splits into Na+ and Cl– ions. it splits into its component ions. The ions are free to move about in an electrolyte. When a voltage is applied across electrodes placed in the electrolyte, the ions start moving in an orderly fashion.

That is why liquids that have ions, such as acids and solutions of salts and bases, conduct electricity. When an ionic compound melts, it breaks up into ions, which flow when a voltage is applied.

Hence, the water do not contain electrolyte, to conduct electricity. without electricity bulb do not glow.
