If the tester is put in distilled water, the bulb of the tester does not glow. This shows that distilled water does not conduct electricity. But when salt is dissolved in distilled water and again tested, the bulb glows which shows that water containing salts conduct electricity.

Reasons why the bulb of a tester does not glow properly when dipped in distilled water:
Insulating properties of distilled water:
- Distilled water is a poor conductor of electricity due to its lack of ions.
- Electricity requires ions to flow through a solution, and distilled water lacks these ions, leading to poor conductivity.
Lack of ions:
- Ions are necessary for the flow of electricity through a solution.
- Since distilled water is devoid of ions, it hinders the flow of electricity, resulting in the bulb not glowing properly.
Purity of distilled water:
- Distilled water is highly pure and lacks impurities that could facilitate the flow of electricity.
- Impurities in water, such as salts or minerals, can act as conductors and enhance the conductivity of the solution.
Conclusion:
- The lack of ions and impurities in distilled water makes it a poor conductor of electricity, causing the bulb of a tester to not glow properly when dipped in it.
