Question

8. Which of the following water is a bad conductor of electricity?

• A. distilled water
• B. water obtained in ion exchange process
• C. mineral water
• D. Both (a) and (b)

Answer 1

The correct option is D

Both (a) and (b)

Explanation for correct option:

(A) Distillation of water involves evaporation and condensation leaving behind the impurities.

(B) Demineralised water is obtained from the ion exchange process which removes all the minerals.

Hence they do not conduct electricity.

Explanation for incorrect option:

(C) Mineral water is a good conductor of electricity because it contains minerals that are responsible for electrical conductivity.

Hence option (D) is correct.
